Find the missing measures
Brrunno [24]

Answer:

y=107

x=73

z=73

Step-by-step explanation:

y and 107 are vertical angles, which means that they're the same value because they're vertically across from each other.

107 and x are supplementary angles, so x=180-107 or 73.

x and z are also vertical angles, so x=z=73.

Can Someone explain how to do this?
zheka24 [161]
1 equals 2. So 2 would be 50 as well.
50+50=100
And there's 360 degrees in total so you'd then subtract 360-100= 260
Then divide by 2 since the other 2 angles are the same
260/2=130
1=50
2=130
3=130
Hope this makes sense! :)
