Interesting question. Let's see.
Rectangular Prism: any box (like a shoe box or a packing box).
Triangular Prism: We're not supposed to give personal answers, but I can't help it with this. When I was growing up, our front door's window had a triangular prism beveled around its edges. What made it so remarkable was that it broke up the light into a rainbow of colors on the floor.
Cylinder. Many drinking glasses are in the shape of a cylinder. Also old fashioned water towers were cylindrical in shape.
Cone: a kitchen funnel is an upside down cone. Some funnels don't have a spout, so that makes them true cones.
Pyramid: The pyramids for the Pharaohs in Egypt.
Sphere: Any ball (beach ball, baseball basketball soccer. Some storage shapes for spices -- technically not a perfect sphere). Planets. The sun. (The earth is almost a perfect sphere).
Answer:
angle 5 is 61°
angle 7 is 61°
Step-by-step explanation:
1. angle 7 + angle 8 = 90° Because they are complementary angles
2. Because of point 1 above, angle 5 + angle 6 = 90°
3. since given angle 6 = 29°
so, angle 5 = 90° - 29° = 61°
4. since given angle 5 = angle 8
so, angle 8 = 61°
5. from point 1 above,
angle 7 + 61° = 90°
so angle 7 = 29°
Answer:
If 22 is an option, go with it. I am pretty certain it is correct.
Step-by-step explanation:
Find pie for both circles
13 x pie = 40.8
6 x pie = 18.8
40.8 - 18.8 = 22
