Answer:
x=12
Step-by-step explanation:
As a straight line is equal to 180. Here, we have one angle given, which is 134. So,
w+134=180
w=46
And the sum of all the angles of a triangle is equal to 180.
By adding all the angles,
8x-10+5x-12+46=180
13x-22+46=180
13x+24=180
13x=180-24
13x=156
x=156/13
x=12
