Question

(Right angle) Trigonometry please help!

Answer 1

Answer:

A = 41.4°

Step-by-step explanation:

Reference angle = A

Length of Adjacent side = 6

Length of Hypotenuse = 8

Apply the trigonometric function, CAH.

Cos A = Adj/Hyp

Substitute

$Cos(A) = \frac{6}{8}$

$A = Cos^{-1}(\frac{6}{8})$

A = 41.4° (approximated to the nearest tenth)
