Find the cos sin and tan of 28 degrees in terms of the variables x, y, and k.
Answers
Answer:
[tex]sin(28) = \frac{y}{k} , cos(28) = \frac{x}{k} , tan(28) = \frac{y}{x}[/tex]
Step-by-step explanation:
For this problem, k is the hypotenuse, x is the side adjacent to 28, and y is the side opposite 28.
I would remember SOH CAH TOA.
S - Sine
O - Opposite
H - Hypotenuse
For this, it shows that the sine of the angle is opposite over hypotenuse. Therefore, y/k.
C - Cosine
A - Adjacent
H - Hypotenuse
For this, it shows that the cosine of the angle is adjacent over hypotenuse. Therefore, x/k
T - Tangent
O - Opposite
A - Adjacent
For this, it shows that the tangent of the angle is opposite over adjacent. Therefore, y/x

What is a percentage increase?The percentage increase formula is the ratio of value increased to the original value and multiplied by 100.
We have,
Ricardo:
At 9 years old = 56 inches tall
At 12 years old = 62 inches tall
The percentage increase is given by:
= (62 - 56) / 56 x 100
= (6 / 56) x 100
= (3 / 28) x 100
= 300 / 28
= 10.7142 %
Rounding to its nearest tenth we get,
= 10.7 %
Thus the percentage increase in Ricardo's height is 10.7%.

B. Yes, because 62 +82 = 122.
C. No, because 62 +82 + 122
O D. No, because 6 + 8 + 12.
Answers
Answer:
the answer is B if wrong sorry
Step-by-step explanation:
62+82=122
No, this triangle is not a right angled triangle because 12²≠6²+8² .
What is Pythagoras theorem?
The Pythagoras theorem states that if a triangle is right-angled, then the square of the hypotenuse is equal to the sum of the squares of the other two sides.
Formula of Pythagoras theorem:
[tex]Hypotenuse ^{2} = Perpendicular^{2} +Base^{2}[/tex]
According to the question
The side lengths of a triangle : 6 , 8 , 12
Now according to Pythagoras theorem
If it is a right angled triangle then its sides should follow Pythagoras theorem
i.e
[tex]Hypotenuse ^{2} = Perpendicular^{2} +Base^{2}[/tex]
[tex]12 ^{2} = 8^{2} + 6^{2}[/tex]
but
144 ≠ 64 + 36
144 ≠ 100
Therefore, it is not a right angled triangle .
Hence, This side lengths of a triangle is not a right angle triangle because 12²≠6²+8² .

What are the possible values of the missing term in the geometric sequence?
4, _, 9, ...
Answers
==========================================================
Explanation:
r = common ratio
To get any term in a geometric sequence, we multiply the previous term by r.
So that means 4r is the second term, since 4 is the first term.
The third term is (4r)*r = 4r^2, which is equal to 9 as given to us.
4r^2 = 9
4r^2 - 9 = 0
(2r)^2 - (3)^2 = 0
(2r - 3)(2r + 3) = 0 ... difference of squares rule
2r-3 = 0 or 2r+3 = 0
2r = 3 or 2r = -3
r = 3/2 or r = -3/2
r = 1.5 or r = -1.5
We can use each r value to find the possible second term
S = 4r = 4*(1.5) = 6
S = 4r = 4*(-1.5) = -6
The second term is either 6 or -6.
We could have this sequence: 4, 6, 9, ...
Or we could have this sequence: 4, -6, 9, ...
The possible values of the missing term in the geometric sequence should be considered as the 6 or -6.
Calculation of the missing values:Since
r = common ratio
For get any term in a geometric sequence, we have to multiply the previous term by r.
Here first term is 4 so the second term be 4r
And, the third term be [tex](4r)*r = 4r^2[/tex] , that is equivalent to 9
[tex]4r^2 = 9\\\\4r^2 - 9 = 0\\\\(2r)^2 - (3)^2 = 0[/tex]
(2r - 3)(2r + 3) = 0
2r-3 = 0
or
2r+3 = 0
2r = 3 or 2r = -3
[tex]r = 3/2\ or\ r = -3/2[/tex]
r = 1.5 or r = -1.5
Now
S = 4r = 4(1.5) = 6
S = 4r = 4(-1.5) = -6
Hence, The possible values of the missing term in the geometric sequence should be considered as the 6 or -6.

1. Convert the problem to an equation using the percentage formula: P% * X = Y.
2. P is 10%, X is 150, so the equation is 10% * 150 = Y.
3. Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.
