Answer 1

Answer:

46°

Step-by-step explanation:

Since the 3 sides are given we can use any of the 3 trig. ratios to solve.

Using the tangent ratio in the right triangle

tan ? = $\frac{opposie}{adjacent}$ = $\frac{42}{40}$, thus

? = $tan^{-1}$ ($\frac{42}{40}$ ) ≈ 46° ( to the nearest degree )
