Question

4. In given quadrilateral ABCD, AB || CD. Find the value of x, y, z and a.​

Answer 1

your ans is

angle z = 47

angle y = 33

angle a = 100

angle x = 100

it's explanation in above image

Answer 2

Answer:

a = 100°

x = 100°

y = 33°

z = 47°

Step-by-step explanation:

angle D + angle A = 180° (co-interior angles)

(47° + 33°) + x = 180°

80° + x = 180°

x = 180° - 80°

x = 100°

y = 33° (alternate interior angles)

z = 47° (alternate interior angles)

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

(y + z) + a = 180°

(33° + 47°) + a = 180°

80° + a = 180°

a = 180°-80°

a = 100°
