Answer:
4. obtuse
5. obtuse
6. acute
7. acute
8. obtuse
Step-by-step explanation:
4. This angle is greater than a right angle (because it extends farther than one), so this is obtuse.
5. This angle is greater than a right angle, so this is obtuse.
6. This angle is smaller than a right angle (because it extends less than one), so this is acute.
7. This angle is smaller than a right angle, so this is acute.
8. This angle is greater than a right angle, so this is obtuse.
Area=pi times radiius^2
radius=diameter/2
diamter=5
radius=5/2=2.5
pi=3.14 aprox
area=3.14 times 2.5^2
area=3.14 times 6.25
area=19.625 ft^2
round
19.6 round up
20
the answer is 20 ft^2
Answer:
20t+20 ≤ 93
20t ≤ 73
t ≤ 73/20, or 3.65

Your calculator will come back with 0.8
So now you need only add on the 2
2 + 0.8 = 2.8 <<<<< Answer
