Please help ASAP. PRE ALGEBRA
elena-14-01-66 [18.8K]

Answer:

90, 90, 90, 135, 135

Step-by-step explanation:

The sum of the measures of all angles is 540 deg.

The measures of the angles are: x - 45, x - 45, x, x, x - 45.

Add the expressions of the measures of the angles and set equal to the sum of the measures, 540 deg. Then solve for x. Then use the value of x to find each angle measure.

x + x + x - 45 + x - 45 + x - 45 = 540

5x - 135 = 540

5x = 675

x = 135

x - 45 = 135 - 45 = 90

Answer: 90, 90, 90, 135, 135
