Question

26.In figure 16, lines AB and CD intersect at M.PM | AB. If ZDMB = 20°, find the angles a,b,c and d.​

Answer 1

Answer:

a is 20

b is 160

c is 70

d is 90

Answer 2

Answer:

Angle a = 20° (vertically opposite angle)

angle b + 20° = 180°

angle b = 180 - 20 = 60°

angle d = 90° (given)

angle c + angle d + angle a = 180°

angle c = 70°
