Question

Can someone help me!

Answer 1

m∠A = 48.81°

Explanation:

Given triangle is a right triangle and we have to measure ∠A.

Since, opposite side and adjacent sides of angle A has been given

So we will apply tangent rule to get the measure of angle A.

tan(∠A) =
`\frac{\text{Opposite side}}{\text{Adjacent side}}`

tan(∠A) =
`(8)/(7)`

∠A =
`\text{tan}^(-1)((8)/(7))`

∠A = 48.814

≈ 48.81°
