Answer 1

Answer:

your answer is ‹b ok this is your answer

Answer 2

Answer:

m∠D = 60°

Step-by-step explanation:

Use the CAH from SOHCAHTOA.

CAH is cosΘ = $\frac{Adjacent}{Hypotenuse}$

Substitute the given values into the above formula.

The adjacent side of ∠D measures 8, and the hypotenuse (the longest side of the right triangle) measures 16.

cosΘ = $\frac{Adjacent}{Hypotenuse}$

cos D = $\frac{8}{16}$

D = $cos^{-1}$($\frac{1}{2}$)

D = 60°

Therefore, the m∠D = 60°
