Answer:

The measure inside a triangle always add up to 180, so you would add up the angle we know of so far and then subtract that from 180:

28 + 35 = 63

180 - 63 = 117

The missing angle in triangle 1 is 117!

90 + 32 = 122

180 - 122 = 58

The missing angle in triangle 2 is 58!

Explanation:

Hope it helps! =D
