Grace has a 45 degree upwards angle, then the height of the lighthouse is 14'.
Case A. Kelly is 26 feet from the lighthouse.
The arcTangent of 14/26 is a 28.3 degree angle.
Case B. But if Kelly stood closer to the lighthouse, i.e. 2 feet away, then her angle is arcTangent of 14/2 = 81.9 degrees

Another name for pyramid with an equilateral base, could be a square pyramid. It could also be a triangular pyramid.
I have included a picture of each of these nets to show you the areas that would need to be calculated.
To find the area of the services on an equilateral based pyramid, you would need to find the area of the base, and the area of one triangle (lateral face). All the triangular area's leading up to the point on a pyramid would be congruent.
This means if it is a square pyramid you would have four congruent triangles.
If it is a triangular pyramid you would have three congruent triangles in addition to the triangular base.
Answer: 9 cups of food
Step-by-step explanation:
First find out the amount of food that one puppy eats per day.
Each puppy eats 0.5 cups of food three times a day which means that in total they eat:
= 0.5 * 3
= 1.5 cups of food.
There are 6 puppies in the litter so the total amount of food they eat is:
= 1.5 * 6 puppies
= 9 cups of food
