Question

Can anyone help me?plps

Answer 1

42.5°

Explanation:

Reference angle = θ

Side opposite to θ = 2.7

Hypotenuse = 4

Applying trigonometric ratio, we have:

`sin (\theta) = (opp)/(hyp) = (2.7)/(4)`

`sin (\theta) = 0.675`

`\theta = sin^(-1)(0.675)`

`\theta = 42.4541502`

θ = 42.5° (nearest tenth)
