Anyone help me out please?

? ≈ 52.3°

Step-by-step explanation:

Using the sine ratio in the right triangle

sin ? = = , thus

? = ( ) ≈ 52.3° ( to the nearest tenth )

≈ 52.3

Step-by-step explanation:

You are given the opposite and hypotenuse side, leading you to use sin. However, since you're trying to find the angle measurement, you use the inverse of sin:

Set it up like this:

When you solve, you get:

52.34

Round to the nearest tenth:

52.3

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

126 maybe. sorry
