Answer:20Step-by-step explanation:The two given and marked angles add up to 90.A = xB = 3x + 10A + B = 90 Substitute for A and B. A and B are just letters I gave things. x + 3x + 10 = 90 Combine the left4x + 10 = 90 Subtract 10 from both sides.4x +10-10 = 90-10 Combine4x = 80 Divide by 44x/4=80/4x = 20
