Question

In a parallelogram abcd , in a parallelogram ABCD angle A is equals to 3 X + 23 angle b is equal to 2 X + 17 then angle D is

Answer 1

Answer:

73

Step-by-step explanation:

∵ABCD is a parallelogram

angle A + angle B = 180 (co interior angles)

3x + 23 + 2x + 17 = 180

5x + 40 = 180

5x + 140

x = 28

∵ABCD is a parallelogram

angle b = angle d (property of parallelogram) - opp. angles are equal

2x + 17 = angle D

2 x 28 + 17 = angle D

73 = angle D
