Question

How to you find the measure of angle m<11 and m<12?

m<11=4x
m<12=2x-6

Answer 1

again, these two angles are supplementary

Answer 2

so the measures of the angles add to 180

Answer 3

m < 11 + m < 12 = 180

4x + (2x-6) = 180

4x + 2x - 6 = 180

Keep going to solve for x

Answer 4

So 4x +2x-6 must equal 180.

Answer 5

Then substitute x into 4x and 2x-6 to find the measures of the angles.

Answer 6

m<11=124
m<12=56

Answer 7

both are correct, nice job

Answer 8

Thanks. So if both angle measures are supplemtary angles then I make the angle measures equal to 180?

Answer 9

yes, if the angles are supplementary, then they add to 180

Answer 10

Okay, I think I got it now.

Answer 11

ok great

Answer 12

What does a commplemtary angle look like?

Answer 13

they add to 90 degrees

Answer 14

so they form a right angle

Answer 15

Ohh, okay. Thanks for all your help. You helped a lot.
