Find the measure of the unknown angle. 1. Add the two know angles:___+___=___

2. Subtract the sum from 180°: 180-___=___

3. The measure of the unknow angles is:_

N = 53°

Step-by-step explanation:

1. 55 + 72 = 127°

2. 180° - 127° = 53°

3. Angle N is 53°

I hope this helps in any way:)

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.
