Answer:


x\approx 49.6^(\circ)

Explanation:

In any right triangle, the tangent of an angle is equal to its opposite side divided by its adjacent side.

For angle
x:

  • Opposite side is 40
  • Adjacent side is 34

Therefore, we have:


\tan x^(\circ)=(40)/(34)

Take the inverse tangent of both sides to solve for
x:


\tan^(-1)(\tan x)=\tan^(-1)((40)/(34)),\\x=\tan^(-1)((40)/(34)),\\x=49.63546343\approx \boxed{49.6^(\circ)}

*Recall
\tan^(-1)(\tan x)=x\text{ for } x\in (-90^(\circ), 90^(\circ))
