Question

angle A and angle B
are
supplementary angles
if, angle A = x + 10 ° and angle B = x - 10° , find angle A and angle B

Answer 1

Step-by-step explanation:

x+10+x-10=180

2x-0=180

2x=180

x=180÷2

x=90

x+10=90+10

=100

x-10=90-10

x=80

Answer 2

Step-by-step explanation:

as per given condition

A+B=180

SO

x+10+x-10=180

2x=180

x=180/2

x=90

now angle A=90+10=100degrees

and angle B=90-10=80 degrees
