Hey!!!

Solution,

2x+10+X+5=180 ( sum of co-interior angles)

or, 2x+X+10+5=180

or,3x+15=180

or,3x=180-15

or,3x=165

or, X=165/3

X=55

So the value of X is 55.

Hope it helps...

Good luck on your assignment

STAY SAFE......

Answer:

Explanation:

2x + 10 + x + 5 = 180 (Sum of co-interior angles}

Add the like terms

3x + 15 = 180 {Subtract 15 form both sides}

3x +15 - 15 = 180 - 15

3x = 165 {Divide both sides by 3}

3x/3 = 165/3

x = 55°
