Answer:

1) 55 degrees

2) 90 degrees

3) 105 degrees

Step-by-step explanation:

All triangles equal to 180 degrees. So to find the missing angle measure you have to subtract the two given measures by 180.

First triangle:

180 - 50 - 75 = 55 degrees

Second triangle:

180 - 60 - 30 = 90 degrees

Third triangle:

180 - 45 - 30 = 105 degrees
