Answer:
A = 60
B = 30
Step-by-step explanation:
Complementary angles add to 90 degrees
A = 2B A is twice the measure of B
A + B =90 Complementary angles add to 90 degrees
Substitute the first equation in for the second
A+B =90
2B+B=90
Combine like terms
3B = 90
Divide by 3
3B/3 = 90/3
B = 30
A = 2B
A = 2*30
A = 60
