Question

Help with triangles? Find x, y, and z.

Answer 1

sum of the angles of a triangle is 180.. from the first triangle we have 28+85+x=180. so x=?. @ValentinaT

Answer 2

hei?? @ValentinaT

Answer 3

67, right?

Answer 4

yes

Answer 5

now x+y =180 so what is y/?

Answer 6

x or z?

Answer 7

Because x + y = 180, would be 67 + y = 180, so 180 - 67 = 113. y = 113?

Answer 8

yes correct. now again apply the formula of the sum of the angles of a triangle is 180 degree to the second triangle and get z

Answer 9

113 + 17 = 130, 180 - 130 = 50. z = 50?

Answer 10

correct.:)

Answer 11

Great, thank you! Could you help me with some more?

Answer 12

ok tag me...:)

Answer 13

Alright, @Princer_Jones I got alternate interior?

Answer 14

corresponding angles

Answer 15

Oh, I see! Thank you. Another question?

Answer 16

ok...

Answer 17

Alright.

Answer 18

you know midpoint theorem?

Answer 19

@ValentinaT

Answer 20

It's base = 2(ms), I think.

Answer 21

so apply this theorem and get the value of x

Answer 22

10x-21=2(2x) from here get x

Answer 23

x = 3.5?

Answer 24

yup

Answer 25

Great, thank you for all of your help!
