Question

In the figure below, n || o. Find the values of z and y.

10
(sy - 9)
ܘ 2
Z
74°

Answer 1

z = 106, y = 23

Explanation:

z and 74 is a supplementary angle which is equal to 180 degrees.

z + 74 = 180

z = 106

5y - 9 and z is a vertical angle, so the are equal to

each other.

5y - 9 = z

5y - 9 = 106

5y = 115

y = 23
