Question

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

Answer 1

Answer:

x ≈ 28.8°

Step-by-step explanation:

Using the sine ratio in the right triangle

sin x = $\frac{opposite}{hypotenuse}$ = $\frac{AB}{AC}$ = $\frac{3.9}{8.1}$ , then

x = $sin^{-1}$ ($\frac{3.9}{8.1}$ ) ≈ 28.8° ( to the nearest tenth )
