Question

x=?, y=?
explain your reasoning with a paragraph proof.

Answer 1

x and 85 are supplementary .

Answer 2

the bottom left triangle inside is 180-95

thus we are getting that the bottom left triangle inside is 85

Knowing that the sum of inner angles is 360, you can find y.

Answer 3

im still a little confused..

Answer 4

did you find x ?

Answer 5

x is 95?

Answer 6

yes

Answer 7

Can you find the angle that's right above it ?

Answer 8

would it be 85?

Answer 9

yes.

Answer 10

So, once you found all the angles inside that 4-angles shape, can you find the y ?

hint: sum of angles = 360

Answer 11

108 is y

Answer 12

so how would i explain that in a paragraph for proof?

Answer 13

\[y=360-(85+95+72)=360-252=108\]

Answer 14

Well, just summarize what we did...

Answer 15

ok thanks :) you helped a lot

Answer 16
