Question

<1 and <2 are supplementary angels. m<1 is 4Y+7, and m<2 is 9Y+4. find M<2?

Answer 1

supplementary angles mean that <1 and <2 add up to 180

so

4Y + 7 + 9Y + 4 = 180

first step, solve for Y

Answer 2

i cannot figure this problem out at all and i have tried to but i just cant.

Answer 3

oh okay thanks, ill try that then.

Answer 4

so 13Y+11=180

Answer 5

good so far, now find Y

Answer 6

y=13

Answer 7

good.

now <2 = 9Y + 4 = ?

Answer 8

121

Answer 9

am i right?

Answer 10

yup! that's our final answer
