Question

the angles are supplementary angles. Determine the measures of 1 and 2.

Answer 1

Ok so first of all can you tell me that what is the sum of two supplementary angles

Answer 2

180 degrees

Answer 3

Great ... so now we have :

angle 1 + angle 2 = 180 degrees ..

correct?

Answer 4

That's right

Answer 5

Ok so

angle 1 = 7x-12

angle 2 = x

7x-12 + x = 180

solve for x now

Answer 6

A1 = 7x-12
A1 = 7 * 24 - 12
A1 = 168 - 12
A1 = 156

Answer 7

how did you get x = 24 degrees?

Answer 8

I divided 192 into 8

Answer 9

You have solve first :

7x-12 + x = 180

8x-12=180
8x=192
x=24

Answer 10

and then you may continue

Answer 11

(7x-12) + x = 180 degrees
8x-12 = 180
8x=192
x=192/8
x=24

Answer 12

Right... we have

angle 1 = 7x-12=168-12 = 156

angle 2 = x = 24

Answer 13

Thank You
