Question

2. The sum of the measures of angle X and angle Y is 90. If the measure of angle X is 30 less than (1 point)
twice the measure of angle Y, what is the measure of angle X?
A.) 20°
B.) 35°
C.) 50°
D.) 650

Answer 1

Answer: angle y is 50°

Step-by-step explanation:

t + 2t - 30 = 90

3t -30 = 90

3t = 90+30

t = 120/3 = 40 = angle X

Angle y = 2t-30

y = 2*40-30

=80-30 = 50
