Answer:
42.5°
Step-by-step explanation:
Reference angle = θ
Side opposite to θ = 2.7
Hypotenuse = 4
Applying trigonometric ratio, we have:
[tex] sin (\theta) = \frac{opp}{hyp} = \frac{2.7}{4} [/tex]
[tex] sin (\theta) = 0.675 [/tex]
[tex] \theta = sin^{-1}(0.675) [/tex]
[tex] \theta = 42.4541502 [/tex]
θ = 42.5° (nearest tenth)
