measure of the angle. Find the measures of the angle and its supplement.

Answer 1

@bobwhiz why did you delete your answer?

Answer 2

let x = the angle

so 180 - x is the supplement

Answer 3

because "The measure of the supplement of an angle is 12 more than twice the measure of the angle", we know that

180 - x = 2x + 12

Answer 4

solve that for x and tell me what you get

Answer 5

I do not now how to solve for X

Answer 6

180 - x = 2x + 12

180 - 12 = 2x + x

168 = 3x

x = ??

Answer 7

x = 56?

Answer 8

so if x = 56, then what is 180 - x

Answer 9

124?

Answer 10

good, the original angle is 56 degrees

the supplement is 124 degrees

Answer 11

when you did "180 - x = 2x + 12

180 - 12 = 2x + x" how did you know how to do that?

Answer 12

like how to you simplify

Answer 13

180 - x is the supplement

Answer 14

oh i see

Answer 15

I added x to both sides

and I also subtracted 12 from both sides

Answer 16

oh ok thank you

Answer 17

yw

Answer 18

wait is the supplement 180-x or 124 degrees?

Answer 19

180-x is the supplement of x

124 is the supplement of 56

Answer 20

the final answer they want is 124 for the supplement

but you use 180 - x to get there

Answer 21

ohh thank you

Answer 22
