Question

Solve for x. Round to the nearest tenth of a degree, if necessary.​

Answer 1

Answer:

x ≈ 54.8°

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan x = $\frac{opposite}{adjacent}$ = $\frac{PQ}{QR}$ = $\frac{7.1}{5}$ , then

x = $tan^{-1}$ ($\frac{7.1}{5}$ ) ≈ 54.8° ( to the nearest tenth )
