Question

in the trapezium ABCD ,find the measure of of D .if A=55,B=55

Answer 1

Given: The angles A = 55 degree and B = 55 degree

To find: the measure of D.

Solution:

• Let ABCD be the trapezium where AB || CD.

• Then it would be isosceles triangle ad adjacent sides will be same as 55 degree.

• Now angle A + D = 180 degree as co interior angles are supplementary.

• So:

               55 + D = 180

               D = 180 - 55

               D = 125 degree.

Answer:

           So the angle of D is 125 degree.

Answer 2

Step-by-step explanation:

answer = 125°
