Question

2. The sum of the measures of angle X and angle Yis 90. If the measure of angle Xis 30 less than twice the

measure of angle Y, what is the measure of angle X?
O 20°
O 35°
50°
65°

Answer 1

50 degrees

Explanation:

x + y = 90

x = 2y - 30

2y - 30 + y = 90

3y - 30 = 90

3y = 90 + 30

3y = 120

y = 120/3

y = 40

x = 2y - 30

x = 2(40) - 30

x = 80 - 30

x = 50 <====== angle x
