What is the degree measure of z?

A)81°

B)114°

C)130°

D)147°

This question is incomplete.

The diagram was sourced online.

D) 147°

Step-by-step explanation:

The sum of angles in a triangle = 180°

There is a missing angle in the triangle which will be represented as x

Hence,

180° = 114° + 33° + x°

180° = 147° + x°

x° = 180° - 147°

x° = 33°

To find z

We know the angle on a straight line = 180°

z + 33° = 180°

z = 180° - 33°

z = 147°

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.
