Question

Find the measure of the missing angle *

Answer 1

Answer:

≈ 49.9° and ≈ 71.0°

Step-by-step explanation:

Using the sine ratio in the right triangle

sin? = $\frac{opposite}{hypotenuse}$ = $\frac{13}{17}$ , then

? = $sin^{-1}$ ($\frac{13}{17}$ ) ≈ 49.9° ( to the nearest tenth )

----------------------------------------------------------------

Using the cosine ratio in the right triangle

cos? = $\frac{adjacent}{hypotenuse}$ = $\frac{14}{43}$ , then

? = $cos^{-1}$ ($\frac{14}{43}$ ) ≈ 71.0° ( to the nearest tenth )
