Answer 1

Answer: LET THE ANGLE A,B,C,D RESPECTIVELY.

A+D=180  -[1]

B+C=180  -[2]

A-D=40 -[3]

B-C=20 -[4]

ADDING EQNS [1] AND [3]-

[A+D=180] + [A-D=40]

2A=220

A=110

PUTTING VALUE OF [A] IN EQN [3]

110-D=40

D=70

TO FIND THE VALUES OF ANGLE [B] AND [C].. REPEAT THIS PROCESS AGAIN AND THEN YOU HAVE ALL MEASURES OF ANGLES.
