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.

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.

so we have the equation 3x + 2(x + 30) = 540 solve this for x
