Explanation:

All these problems can be solved with two simple rules

1) intersecting lines create two pairs of opposite equal angles

2) The sum of internal angles in a triangle is 180°

the rest is simple math manipulation.

I'll set up one for you

12) 81 + (x + 5) + (6x - 11) = 180

once you have x, then the center angles are z = 6x - 11 and the other triangle is

z + (y + 14) + (4y - 18) = 180

the awnser is d i think
