Can anyone help me?plps

Answer 1

Answer:

42.5°

Step-by-step explanation:

Reference angle = θ

Side opposite to θ = 2.7

Hypotenuse = 4

Applying trigonometric ratio, we have:

$sin (\theta) = \frac{opp}{hyp} = \frac{2.7}{4}$

$sin (\theta) = 0.675$

$\theta = sin^{-1}(0.675)$

$\theta = 42.4541502$

θ = 42.5° (nearest tenth)
