Question

find the value of x in the following figure
​

Answer 1

Step-by-step explanation:

4x - 5 + 2x + 15 = 180

6x + 10 = 180

6x = 170

x = 170 / 6

x = 85 / 3

Answer 2

Answer:

let

4x-5 be angle 1

and

2x+15 be angle 2

two angle on on a line make suplementry angle 180⁰

so

4x-5+2x-5=180

4x+2x-5+5=180

=8x-0=180

=8x=180

=x=180/8
