Question

Can someone help me plz

Answer 1

Answer:

75°

Step-by-step explanation:

Recall: SOH CAH TOA

Reference angle = ? = θ

Side length opposite to reference angle = 27

Hypotenuse length = 28

Apply SOH, which is:

$sin(\theta) = \frac{Opposite}{Hypotenuse}$

Substitute

$sin(\theta) = \frac{27}{28}$

$\theta = sin^{-1}(\frac{27}{28})$

$\theta = 75 degrees$ (nearest degree)
