Answer 1

Step-by-step explanation:

angle B = 90

angle D = 360 - (140+90+90) = 40

Answer 2

Step-by-step explanation:

Angle sum property of trapezium = 360°

Angle A = 90°

Angle C = 140°

Let angle D be D

90°+140°+D+B = 360°

D+B = 360°-230°

D = 130°-B.

B = 130°-D.

NOW PUT THE EQUATION AND SOLVE.
