Question

find the measure of an angle whose measure is 20 degrees more than its supplement

Answer 1

supplementary angles are 180 degrees

Answer 2

so its 180-x=20

Answer 3

I would say 180 +20

Answer 4

actually its 180-x=20

Answer 5

no teresaa, that angle x - 20 = 180 - x (it's supplement angle)

Answer 6

maybe x+(x+20)=180

Answer 7

The supplement of an angle takes it up to 180 degrees

Answer 8

so how do i solve

Answer 9

reading it literally...
the measurement of an angle (x) is 20 more than its supplement
x=180-(x+20)

Answer 10

x=180-x-20

Answer 11

2x=160

Answer 12

You get to do the last step

Answer 13

eulergroupie, you are solving for x and x in your equation is ..."it's suplement", not the angle itself

Answer 14

tamtoan can u tell me how u think its done

Answer 15

It is strange wording...

Answer 16

It is confusing... I would say that we have two angles that are supplementary.
One is 100 degrees and one is 80 degrees. Together they make 180 degrees. That is the supplement.
The angle that is 100 degrees is 20 more than 80 degrees. Sorry to be so confused... but I think that "the angle" that would be 20 more than its supplement would be 100 degrees. Whew!

Answer 17

@tamtoan had a good point... my equation found the other angle.

Answer 18

teresass, follow eulergroupie and you will understand, he explained clearly there :)
