Answer:
1. Obtuse angle
2. 5
3. 117
Explanation:
1. Any angle that is wider than 90 degrees is obtuse.
2. 180 = straight angle/line so, 180-140=40 8x5=40 so x=53. ***Supplementary angles are one angle that is 180 so, 180-63= 117**
2. 180 = straight angle so, 180-140=40 8x5=40 so x=5
3. Supplementary angles are one angle that is 180 so, 180-63= 117
