Question

if each of the following figure, find the value of x if l
|| m and a || b​

Answer 1

Answer:

x = 4

Step-by-step explanation:

17x + 4º = 12º + 15x (As we learnt that corresponding angles are equal).

Solving it-

  17x + 4 = 12 + 15x

17x - 15x = 12 - 4

      2x    = 8

       x      = 4

Checking:    

(17 x 4) + 4   = 72

12 + (15 x 4) = 72

Therefore the value of x is 4.

Hope this helps...
