Question

In ABCD, as compared to the
measure of A, the measure of
B exceeds by 10°. the measure
of C exceeds by 20° and the
measure of D exceeds by 10°
Find the measure of all the angles
of ABCD​

Answer 1

angle A+angle B+angle C+angle D=360°

angle A+10°=angle B

angle A+20°=angle C

angle A+10°=angle D

So, A+ A+10°+ A+20°+ A+10°=360°

= 4A+40°=360°

=4A=360-40

=4A=320

A=320/4

A=80°

B=80°+10°=90°

C=80°+20°=100°

D=80°+10°=90°

The measure of all the angles of ABCD are 80°, 90°, 100° and 90° respectively
