Isosceles trapezoid the measure of d is 53 degrees what is angle C angle A angle B?
In an isosceles trapezoid, the base angles (angles A and B in this case) are congruent. Therefore, the measure of angle A and angle B is each half of the measure of angle D.
Angle C is supplementary to angle D, so to find the measure of angle C, subtract 53 degrees from 180 degrees:
Angle C = 180 - 53 = 127 degrees
Since angles A and B are congruent and each is half of angle D:
Angle A = Angle B = 53 / 2 = 26.5 degrees
Therefore, the measures of the angles are:
Angle A = 26.5 degrees
Angle B = 26.5 degrees
Angle C = 127 degrees
Angle D = 53 degrees
