Question

Need help solving this

Answer 1

Answer:

x ≈ 41.6°

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan x = $\frac{opposite}{adjacent}$ = $\frac{JK}{KL}$ = $\frac{80}{90}$ = $\frac{8}{9}$ , then

x = $tan^{-1}$ ( $\frac{8}{9}$ ) ≈ 41.6° ( to the nearest tenth )
