Find the value of x. Round to the nearest degree

ValentinkaMS [17]

Answer:

b. 44°

Step-by-step explanation:

Reference angle = x

Hypotenuse = 21

Adjacent = 15

Apply trigonometric function CAH:

$Cos(x) = \frac{Adj}{Hyp}$

$Cos(x) = \frac{15}{21}$

$x = cos^{-1}(\frac{15}{21})$

x = 44.4153086° ≈ 44° (nearest degree)
