Answer:
∠A = 48.81°
Step-by-step explanation:
Trigonometry:
Opposite side of ∠A and adjacent side of ∠A is given. So, we can use tan ratio to find ∠A.
[tex]\sf tan \ \angle \ A = \dfrac{opposite \ side}{adjacent \ side}\\\\\\tan \ \angle \ A = \dfrac{8}{7}[/tex]
tan ∠A = 1.1428
[tex]\sf \angle A = tan^{-1} \ 1.1428[/tex]
∠A = 48.812
∠A = 48.81°
