First, we imagine a right triangle. Second, we are given that the building is 62 feet tall. Since the height of building is vertical straight - that means the height is opposite side of triangle. It also casts a shadow 21 meters long. Shadow should be the adjacent side because it casts on the ground and not on the air.
If we imagine the right triangle + the problem in our head, we'd get the triangle that the opposite side is 62 feet tall and the adjacent side is 21 meters long.
Use the tangent ratio to find the angle of sun shining.

Substitute adjacent = 21 and opposite = 62 in the ratio.

For this part, you might need a calculator or trigonometric table because some values cannot be exactly found.
From the equation, we should get 71.288 which we round the answer to nearest hundreth and the answer would be 71.29
Answer
Ok so a rectangular prism is the same as a rectangular cuboid.
The surface area is all the areas of the faces added together ->
There are three different faces that occur twice
length -> l
width -> w
height ->h
2( l * w ) + 2( l * h ) + ( w * h )
2 ( 10 * 4.5 ) + 2 ( 10 * 8.75 ) + 2 ( 4.5 * 8.75 ) = 343.75 cm2
Therefore it's A
Hope this helps :P
If 1 cup of chocolate chips weighs about 6 ounces
The recipe calls for 3 1/4 cups of chocolate chips.
We need to multiply 6 by 3 which is 18 ounces plus the 1/4 which is 6 times 1/4 = 1.5 ounces
18 + 1.5 = 19.5 ounces of chocolate chip needed
