I've been trying to think of an equation but I can't seem to find one. I'm trying to do good in math but I suck. Help!?
∠A and ∠B are complementary angles. The measure of ∠A is twice the measure of ∠B.
Write and equation to represent the complementary angle relationship between ∠A and ∠B. Use the equation to find the measure of ∠A and ∠B. Show all of your work.

✔ 最佳答案
complementary angles add up to 90 deg.If ∠A is twice ∠B, then:
∠A = 2∠B
∠A + ∠B = 90
2∠B + ∠B = 90
3∠B = 90
∠B = 30
∠A = 60

Complementary angles add to 90 degrees.
2x + x = 90
3x=90
x=30
60 and 30
2x + x = 90
3x=90
x=30
60 and 30
