In the figure below, n || o. Find the values of z and y.
10
(sy - 9)
ܘ 2
Z
74°

z = 106, y = 23

Step-by-step 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

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
