Question

Angles A and B together create a 90° angle. ∠A = 4x −10 and ∠B = 2x − 20. Find the angle measures (what will

Answer 1

see below

Explanation:

A+ B = 90

4x-10 + 2x-10 = 90

Combine like terms

6x -20 = 90

Add 20 to each side

6x -20+20 = 90+20

6x = 110

Divide by 6

6x/6 = 110/6

x = 55/3

A = 4x-10 = 4(55/3) -10

A=63 1/3

B = 2x-10 = 2(55/3) -10

26 2/3
