Use the inverse of tangent to find the approximate measure of angle A rounded to the nearest whole degree A 23 B 21 C 43 D 67 class=

Respuesta :

Answer:

D

Step-by-step explanation:

using the tangent ratio in the right triangle

tan A = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{12}{5}[/tex] , then

∠ A = [tex]tan^{-1}[/tex] ( [tex]\frac{12}{5}[/tex] ) ≈ 67° ( to the nearest whole degree )
