Question

In the triangle below, determine the measure of angle A

Answer 1

Answer:

m∠A ≈ 65°

Step-by-step explanation:

We use the inverse trig ratio tan⁻¹ to solve this problem.

m∠A = tan⁻¹($\frac{15}{7}$) --- plug in opposite and adjacent sides of A into tan⁻¹

m∠A ≈ 65° --- solve tan⁻¹($\frac{15}{7}$) with calculator
