Answer:
144
Step-by-step explanation:
Because the horizontal lines are parallel <7 is the same as <4. Because <1 and <7 are on a straight line they must add up to 180. <7 + 36 = 180 so <7=144 so <1 is also 144.
Thats going to be 12x
Since all triangles equal 180 degrees. You will subtract (128 + 23) from 180.
180 - 146 is 34 degrees.
