Question

How to you find the angle measure of m<9 and m<10?

m<9=2x-4
m<10=2x+4

Answer 1

How are angles 9 and 10 related? Are they supplementary? Complementary?

If there's a picture, please post it

Answer 2

ok so they are supplementary

Answer 3

this means that

m < 9 + m < 10 = 180

(2x-4) + (2x+4) = 180

Answer 4

Tell me what you get when you solve for x

Answer 5

45

Answer 6

good, now plug this into 2x-4 to get what?

Answer 7

86

Answer 8

so that's the measure of angle 9

Answer 9

do the same for 2x+4 to find the measure of angle 10

Answer 10

94

Answer 11

good, so angle 9 is 86 degrees and angle 10 is 94 degrees

Answer 12
