Question

6. ∠A and ∠B are vertical angles. M∠B= (3x+4)° and m∠A = (x+48)° find the measure of angle A

Answer 1

In Triangle

ABC with the right angle at C, let a,b, and c be the opposite, the adjacent, and the hypotenuse of ∠A. Then, we have

sin A=ac⇒m∠A=sin−1(ac)

sin B=bc⇒m∠B=sin−1(bc)

I know its not the answer but I hope it was helpful
