Answer:

1) 140 2)68 3) 125 4) 140

Step-by-step explanation:

for these, because you're trying to find the angle from 180 degrees, you would subtract the angle on the 180 degree line from 180.

1) 180-40 = 140

2) 180-112 = 68

3) 180-55 = 125

4) 180-40 = 140

Hope this helps!

The exterior is kinda of going to be the same from so of the shapes but you have to get the legth & the hight.
