In the triangle below, determine the measure of angle A

Answer:
m∠A ≈ 65°
Step-by-step explanation:
We use the inverse trig ratio tan⁻¹ to solve this problem.
m∠A = tan⁻¹([tex]\frac{15}{7}[/tex]) --- plug in opposite and adjacent sides of A into tan⁻¹
m∠A ≈ 65° --- solve tan⁻¹([tex]\frac{15}{7}[/tex]) with calculator
