Answer:

x = 17

Explanation:

Hello There!

We can solve for x using trigonometry

We are given two angles and 1 side length

lets use angle 28

We can find x using cosine


cos=(adjacent)/(hypotenuse)

All we have to do is plug in the given or known information

we know the the adjacent of 28 is 15 and we are looking for x

so we can solve for x using this equation (let x = hypotenuse)


cos28=(15)/(x)

step 1 divide each side by 15

15/cos28

15x/15=x

we're left with


x=(15)/(cos28) \\\\(15)/(cos28) =16.98855076\\so\\x=16.98855076

our final step would be to round to the nearest tenth

x = 17
