Question

What is the measure of angle R?

Answer 1

Answer:

m<R = 22.62°

Step-by-step explanation:

Reference angle = R

Opposite = 5 cm

Hypotenuse = 13 cm

Apply the trigonometric function SOH:

Sin R = Opp/Hyp

$Sin (R) = \frac{5}{13}$

$R = sin^{-1}(\frac{5}{13})$

R = 22.6198649°

m<R = 22.62° (nearest hundredth)
