A triangle is said to be right angle if one of the angles is 90 degrees, the value of the side x for the given right angle triangle is 50.51.
What is a triangle?A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.
The sum of all three angles inside a triangle will be 180° .
The given right-angle triangle has the following sides,
AC = Base
BC = Perpendicular
AB = Hyp.
By tan function,
Since,tanθ = Perp/Base
tan29° = 28/x
x = 50.51
Hence, "A triangle is said to be right angle if one of the angles is 90 degrees, the value of the side x for the given right angle triangle is 50.51".

What is the Pythagorean theorem?Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal to the square of the sum of the other two sides.
According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.
Given that It is 163 cm from your eyes to your toes. You're standing 220 cm in front of a tall mirror.
The distance between the image of toes and eyes will be calculated as,
H² = P² + B²
H= √(P² + B²)
H = √(163² + 220²)
H = √(26569+48400)
H = √74969
H = 273.80 cm
Therefore, the distance between the eyes and the distance to the image of the toes will be 273.80 cm.

John is in charge of feeding the pigs and cows on the farm. The cow's food costs twice as much as the pig's food. There are 46 cows and 22 pigs on the farm. John has an $860 budget for food a month. How much can John spend on food for each cow per month?
Answers
The amount John will spend on food for each cow per month is approximately 15.08 dollars
How to find the how much each cow feed per month?John is in charge of feeding the pigs and cows on the farm.
The cow's food costs twice as much as the pig's food.
Let
x = cost of pigs food
y = cost cow's food
Hence,
y = 2x
There are 46 cows and 22 pigs on the farm. John has an $860 budget for food a month.
46y + 22x = 860
Therefore, let's combine the system of equation.
y = 2x
46y + 22x = 860
46(2x) + 22x = 860
92x + 22x = 860
114x = 860
x = 860 / 114
x = 7.5 dollars
y = 2(7.54) = 15.08 dollars
Therefore, the cost of food for each cow is 15.08 dollars

How to solve Trigonometric Ratios?The 6 main trigonometric ratios of a right angle triangle are;
Sine θ = length of the opposite leg / length of the hypotenuse
Cosine θ = length of the adjacent leg / length of the hypotenuse
Tangent θ = sine θ/cosine θ = opposite leg / adjacent leg.
cosecant θ = 1 / sine θ = hypotenuse / opposite leg
secant θ = 1 / cosine θ = hypotenuse / adjacent leg
cotangent θ= 1 tangent θ = adjacent leg / opposite leg.
Now, we are told that the angle formed is 53.13°. Since the options are either arctan or arccos, we will use them to verify the angles;
cos 53.13° = 0.6
tan 53.13° = 1.33
They are both positive and it means both x and y values are positive since we are told that it involves the positive x-axis.

Mr. Abbas has bought a Villa in Saar recently for 80,000 BD. He wants to sell it at a 40% profit. House prices are projected to rise on average by 7% a year.
i) How many years will Mr. Abbas have to wait before selling?
Answers
The 80,000 BD Villa in Saar Mr. Abbas plans to sell at a 40% profit , with the annual house price growth rate of 7% (compounded) gives the number of years Mr. Abbas has to wait as approximately 5 years
What is the growth rate on an value?The growth rate is the rate at which the value changes within a specified period.
The amount Mr. Abbas bought the Villar in Saar = 80,000 BD
The profit at which he intends to sell it = 40% = 0.4
The rate at which the house prices rise on average = 7 % per annum
The formula for future value, FV is presented as follows;
[tex]FV = PV\cdot \left(1+\dfrac{r}{100} \right)^n[/tex]
Where;
FV = The future value = 80,000 BD + 0.4 × 80,000 BD = 112,000 BD
PV = The present value = 80,000 BD
r = The rate at which the house prices increases annually
n = The number of years
Which gives;
[tex]112,000 = 80,000\cdot \left(1+\dfrac{7}{100} \right)^n[/tex]
[tex]n = \dfrac{ln\left(\dfrac{112,000 }{80,000}\right) }{ln\left(1+\dfrac{7}{100} \right) } \approx 5[/tex]

A line has length but no width, making it a one-dimensional figure. A line is made up of a collection of points that are endlessly stretched in the opposing directions.
Main body:
The slope-intercept form is
y=mx+b, where
m is the slope and b is the y-intercept.
y=mx+b
Using the slope-intercept form, the slope is −2.
m=−2
To find an equation that is parallel, the slopes must be equal. Find the parallel line using the point-slope formula.
Use the slope −2 and a given point (0,0) to substitute for
x₁ and y₁ in the point-slope form
y−y₁=m(x−x₁)
, which is derived from the slope equation
m=(y₂−y₁)/(x₂−x₁).
y−(0)=−2*(x−(0))

For each the level of output for 15th year using per year constant increase in production .
Answers
Answer:
6922 TV sets
Step-by-step explanation:
You want the production in the 15th year if production in the first year is 1000 and it increases yearly by a constant amount. The total production in the first 10 years is 29035.
Arithmetic seriesAn arithmetic series is one that has a constant difference from one term to the next. If a1 is the first term of the series, and d is the common difference between terms, the n-th term is ...
an = a1 +d(n -1)
And the sum of n terms is ...
Sn = (2a1 +d(n-1))(n/2)
ApplicationTo find the 15th term, we can make use of the given values to find the common difference, then use the formula for the n-th term.
S10 = (2(1000) +d(10 -1))(10/2) . . . . . sum formula with a1=1000
29035 = 10000 +45d . . . . . . . . . . . simplified
d = (29035 -10000)/45 = 423 . . . . the increase in production each year
Production in the 15th year is ...
a15 = 1000 +423(15 -1) = 1000 + 5922 = 6922
The output in the 15th year was 6922 TV sets.

The number of parks per capita when there is the total population of 870,000 people and there are 212 parks is 4,103.77358.
What is per captia?
“Per capita” is a Latin term that means “per head.” This term is used to express the average per person, the term “per capita” is occasionally used in statistics instead of “per person.”
On a given case, the per capita parks for population can be calculated by dividing total population by total parks.
According to the given illustration,
Total population of city = 870,000
Total Parks= 212
Calculation of parks per capita in the city of Indianapolis:
Per capita shops = Total population/ Total shops
Per capita shops =870,000/212
Per capita shops = 4,103.77358
Therefore, the number of parks per capita is 4,103.77358.

Nice work on selecting "invalid" as the correct answer.
The reason why this argument is invalid is because the 'x' could be in circle B or could be outside circle B. There's simply not enough information.
The venn diagram would either be (A) or (D).
The only information we know is that Fred is does not live in San Francisco, so the 'x' will not be placed inside circle A.
Ignore any diagram where x is on the edge of a circle. That isn't allowed in venn diagrams because a person is either in San Francisco, or they aren't (same goes with California). We can't have blurry boundaries like that. This means venn diagrams (B) and (C) are nonsensical.
A scientist mixes water (containing no salt) with a solution that contains 20% salt. she wants to obtain 120 ounces of the mixture that is 15 % salt. How many ounces of water and how many ounces of the 20% salt solution should she use?
Answers
Answer:Say w= the amount of water in oz, then the 60% of the solution is 250 - w
Set up the equation:
Use distributive property first
0.60(250-w) = 0.15 x 250
Isolate to solve for w
150- 0.60w= 37.5
-0.60w= 37.5-150
0.60w= -112.5
w= 187.5 ounces
250-187.5= 62.5 ounces salt solution
Therefore, she must use 187.5 ounces of water and 62.5 ounces of salt solution for her experiment.
