Answer:
15°, 165°, 195°, 345°
Step-by-step explanation:
The reference angle, 15°, is the smallest angle the terminal ray makes with the x-axis. In the first and fourth quadrants, the positive x-axis is the reference line. The angles will be ±15°, or 360°-15° = 345° if you require all angles to be positive.
In the second and third quadrants, the negative x-axis is the reference. That is 180°, so the reference angle will be added to or subtracted from 180° to give 165° or 195°.

Answer: a square with side length 4 inches
a 2 inch by 8 inch rectangle
a heart-shaped base with an area of 16 square inches
Step-by-step explanation: The given height is 5. Any base with an area of 16 square inches will be an acceptable base.
For example, if the circular base had a radius of about 2.257 inches, its area would be 16 square inches
(2.257)² ≈ 5.093
5.093 × 3.1416 ≈ 16
16 × 5 = 80
