Question

1. Z A and B are supplementary angles. If ZB ZA= x + 10º and ZB = x - 10°, find ZA and ZB.​

Answer 1

Answer:

<A = 100, <B = 80

Step-by-step explanation:

angle A and angle B are supplementary angles.

So, <A + <B = 180_____________(1)

given, <A = x+10___(2)  and <B = x -10 ___(3)

So, from, equation (1), (2) and (3)

(x+10) + (x-10) = 180

=> 2x = 180 => x = 90

So, <A = x+10 = 90+10 = 100

<B = x -10 = 90-10 = 80

Answer 2

Answer:

ZA=100

ZB=80

Step-by-step explanation:

Angle A= x+10

Angle B= x-10

Then (x+10)+(x-10)=180

or, x+x+10-10=180

or,2x=180

or,x=180/2

or,x=90

Then, ZA=90+10

=100

And, ZB=90-10

=80
