Find the value of x in the given right triangle

Answers

Answer 1

hi <3

you can use the sine rule in this.

first calculate the missing angle in the triangle.

we know the angles in a triangle sum to 180 so:

180 - 37 - 90 = 53

now, simply input these values into the sine rule

10/sin(53) = x/sin(37)

rearrange for x:

x = (10/sin53) x sin37

solve to get your answer of:

x = 7.5

hope this helps :)

Answer 2

Answer:

tanx=opposite side

adjacent side

tan(37)=x

x=tan(37)x10 (take cross multipication)

x=(0.753554)x10

x=7.53554

x=8

I need help with this math question for the extra credit part of my homework. use the two step and multi-step method and if you can thanks for helping me

Answers

(3x-5) + 2x = 90

3x + 2x + 5 = 90

Combining like terms

5x = 90 - 5

5x = 85

X = 85/5

X = 17

Answer:

X = 19

2 * 19 = 38 degrees

3 * 19 - 5 = 52 degrees

Step-by-step explanation:

3x-5+2x = 90

5x = 90+5

X = 95/5

X = 19

Answers

Answer: b = 8

Step by step explanation :

Step 1 : Multiply by 4 on both sides of the equation.
B/4 times 4 = 2 times 4
Multiplying by 4 and dividing by 4 cancel each other out, so we’re left with b = 2 times 4, or b = 8.

Gina rented a truck for one day there was a base fee of 12.75 there was an additional charge of 20 cents for each mile driven total cost c (in dollars) for driving x miles is given by the following function
C(x)=0.20x+12.65
What is the total rental cost if jina drove 50 miles?

Answers

Answer:

$22.75

Step-by-step explanation:

The function is:

C(x) = 0.20x + 12.75

Find C(50) for 50 miles:

C(50) = 0.20*50 + 12.75C(50) = 22.75

Given function:-

C(x)=0.20x+12.65

We have to find value at 50

[tex]\\ \sf\longmapsto C(50)[/tex]

[tex]\\ \sf\longmapsto 0.20(50)+12.65[/tex]

[tex]\\ \sf\longmapsto 10+12.65[/tex]

A new car, valued at 28,000 depreciates at 9% per year. What is the value of the car one year after purchase

Answers

Answer:

$25,480

Step-by-step explanation:

9% of 28,000 is 2,520. "Depreciates" means we must subtract. When we subtract this number from the initial value of the car which is 28,000 we get 25,480, which would be how much the car is worth after one year.

hope this helps!

So there's 2 types of depreciation you often will come across, one is compound and one is simple.

For compound : A=P(1-i)^n

For simple A=P(1-in)

NOTE: A is amount after depreciation, P is amount before depreciation, n is number of years and i is the rate of depreciation.

Now if your depreciation is compound then:

A=P(1-i)^n

A=28000(1- 0.09)^1

A= 25480

If it's simple depreciation

A=P(1-in)

A= 28000(1- 0.09x1)

A= 25480

Now these are your solutions

In the figure below, which term best describes point X?

A. Circumcenter
B. Orthocenter
C. Centroid
D. Incenter

Answers

Please provide a picture of the figure

In the given figure, the point X represents centroid. The correct option is C.

What is centroid?

A centroid is the point of intersection of all the medians of a triangle in geometry. The medians of a triangle are the line segments that connect each vertex to the opposite side's midpoint.

The centroid is also known as the triangle's "centre of mass" or "centre of gravity" because it is the point at which the triangle could be balanced if cut out of a piece of cardboard or other thin material.

Circumference is defined as the point at which three perpendicular bisectors intersect, which is incorrect because there is no indication of right angles.

The incenter is the point where the angle bisectors of the triangles meet, which is also not shown in the photo.

Thus, the correct option is C.

on a given planet, the weight of an object varies directly with the mass of the object. suppose that an object whose mass is 9 kg weighs 54 N. calculate the mass of another object that weighs 24 N

Answers

We can use the proportion method here

Mass Weight
9 kg 54N
(?) 24 N

Now since it is “directly varied” we can cross multiply to get:

54*x = 24*9
54*x = 216
x= 4

Ans: The mass of an object weighing 24 N is 4 kg

The larger of two numbers is 15 more than three times the smaller number. If the sum of the two

Answers

Step-by-step explanation:

Let the smaller number be x

Greater number = 3x + 15

3x + 15 + x = 63

4x + 15 = 63

4x = 63 - 15

4x = 48

x = 48/4

x = 12

Greater number = 3(12) + 15 = 51

Answer:

Solution,

Let the smaller number be y, then

bigger number=3y+15

Now,

According to question

3y+15+y=63

4y+15=63

4y=63-15

4y=48

y=48/4

y=12

Hence,

smaller number=y=12

greater number=3y+15=3×12+15=51
