Question

In this triangle, what is the value of x?

Answer 1

To find x you can use cosine since you know the adjacent side and the hypotenuse. Remember that for cosine it is adjacent over hypotenuse

cos(x) = $\frac{28}{72}$

cos(x) = $\frac{7}{18}$

To find the x we must take the inverse of cosine:

$cos^{-1}$($\frac{7}{18}$ = x

x = 67.1146...

x ≈ 67.1 degrees
