Question

find the value of x given that the lines/ and m are parallel

Answer 1

Answer:

5x-5+2x+10= 180

7x-5= 180

7x= 175

x = 175/7

x = 25

Answer 2

Step-by-step explanation:

Lines l and m are parallel to each other and cut by a transversal.

So,

Sum of co-interior angles = 180°

(5x-5)+(2x+10) = 180°

5x-5+2x+10 = 180

5x+2x+10-5 = 180

7x+5 = 180

7x = 180-5

7x = 175

x = 175/7

x = 25

The value of x is 25°
