In the triangle below, determine the measure of angle a

m∠A ≈ 65°

Step-by-step explanation:

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

m∠A = tan⁻¹() --- plug in opposite and adjacent sides of A into tan⁻¹

m∠A ≈ 65° --- solve tan⁻¹() with calculator

x+y=90

x=30-y=x

step-by-step explanation:

if you understand you will get the answer
