Question

Can someone help me plz

Answer 1

75°

Explanation:

Recall: SOH CAH TOA

Reference angle = ? = θ

Side length opposite to reference angle = 27

Hypotenuse length = 28

Apply SOH, which is:

`sin(\theta) = (Opposite)/(Hypotenuse)`

Substitute

`sin(\theta) = (27)/(28)`

`\theta = sin^(-1)((27)/(28))`

`\theta = 75 degrees` (nearest degree)
