Answer 1

@hartnn

Answer 2

add all sides than x2 to get ur answer

Answer 3

Sum if interior angles in a triangle = the exterior angle.

This is a theorem that can be easily proved.

so z = x+y

so we need to find x and y.

y is very easy to find, can you try?

Answer 4

Is it 131?

Answer 5

Good JOB!

Answer 6

he added x and y

Answer 7

What?

Answer 8

you aded x and y to get ur answer. wht des x stand for and what does y stand for?

Answer 9

to get 131 x= 16 y= 115

Answer 10

I got 131 because it was right next to "y"?

Answer 11

yes

Answer 12

131 and y are supplementary angles.
can you now find y ?

Answer 13

I don't know how?

Answer 14

yes y equals 60 because 131+60= 190. you get ur answer by adding both. to get the sum for all corners

Answer 15

or for sides

Answer 16

sum of supplementary angles = 180 :)

131 + y = 180

Answer 17

yup

Answer 18

So then now what?

Answer 19

then you will get the 'y'

now to find x,
it is a part of a triangle with 2 angles given.

you can use the property that sum of all 3 angles in a triangle = 180 to get the measure of x .

Answer 20

Is x 49?

Answer 21

x + 42 +73 = 180

and nope

Answer 22

So what I need to solve is "x + 42 +73 = 180" to get my answer?

Answer 23

Which is 65

Answer 24

yes

Answer 25

that gives x

you need z
which is x + y

Answer 26

x = 65
y= 49

z = 49 + 65
