Question 5 (2 points) <br> Find x, y, and z.
Verizon [17]

Answer:

Its actually really easy.

Y is = to 76 degree (Vertically Opposite Angle)

The same way x = z (Vertically Opposite Angles)

So as y = 76 and given angle also 76 we'll add them. You should get 152. Now we know x = z. And we also know angles around a point add up to 360. So 360 - 152 gives 208. Since there are two angles we'll divided them by 2. So you now have 104

Given angle : 76

Y : 76

X : 104

Z : 104
