2. 82 degrees
3. 104 degrees
4. 142 degrees
5.

2. 30
3. 180
4. 25
7.
What is the measurement of this angle in degrees? • 115 degrees
8.
You have a 35 degree angle. Determine the complementary angle AND the supplementary angle. • Complement total is 90, therefore: 90 - 35 = 55, so 55 degrees.
Supplement total is 180, therefore: 180 - 35 = 145, so 145 degrees.

Or, 35 + 55 = 90, and 35 + 145 = 180.
