Question

in a llgm ABCD, angle A is equal to 100 degree find the measure of Angle B and angle D

Answer 1

angle A = 100 degree (given)
therefore, angle C will also be 100 degree. (opposite angles are equal)(opposite to angle A)
Now,
angle B = 80 degree. (adjacent angles are supplementary,i.e. their sum is 180)(adjacent to angle A)
therefore, angle D will also be 80 degree. (opposite angles are equal)(opposite to angle B)

hence, angle A = 100 degree, angle B = 80 degree, angle C = 100 degree, and, angle D = 80 degree.

hope this helps

Answer 2

A=100
C=100( because opp angles of a llgm are equal.
