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 ? = [tex]\frac{opposie}{adjacent}[/tex] = [tex]\frac{42}{40}[/tex], thus
? = [tex]tan^{-1}[/tex] ([tex]\frac{42}{40}[/tex] ) ≈ 46° ( to the nearest degree )
