All triangles are equal to 180 degrees so for number one you would add all the angles that are shown and subtract them by 180 to find the missing angle. For example number one would be. 110+34+e=180. So the answer is e=36

Answer:

1) e = 36 degrees

2) r = 119 degrees

Step-by-step explanation:

There is 180 degrees in a triangle.

110+34=144

180-144=36

e=36

36+25=61

180-61=119

r=119
