Question

HELP BEFORE SCHOOL STARTS!!
SUMMER WORK!
The sum of the angle measures of a pentagon is 540 Degrees. In pentagon ABCDE, angles A, B, and C are congruent, and angle D and E are congruent. The measure of angle D is 30 Degrees greater than the measure of angle A. What is the measure of each angle?
Please help i am freaking out, school starts in 20 minutes.

Answer 1

let measure of angle A be x. Then b = c = x also.
Angle d = x + 30 and as e is congruent to d d is also = x + 30.

Answer 2

so we have the equation

3x + 2(x + 30) = 540

solve this for x

Answer 3

I think I can do that thank you so much

Answer 4

Answer 5

96

Answer 6

A,B,C=96
D,E=126

Answer 7
