Question

What is the value of x, y, and z?

Answer 1

Answer: x = 34º, y = 146º, z = 146º

Explanation:

Adding the angles inside a triangle gives you 180º. So

85 + 61 + x = 180

146 + x = 180

x = 34º

x and y are supplementary, so y = 180 - x = 180 - 34 = 146º.

y and z are equal (vertical angles), so z = 146º.
