Now, the length of v is determine by the Law of Sines:
Sonny lives in a tall apartment building. He looks out his window and spots a car on the road that runs straight toward his buil
ding. His angle of depression to the car is 19°.
Sonny looks farther down the road and spots a dump truck. He estimates that the car is 1000 feet in front of the dump truck. His angle of depression to the dump truck is 9°.
How far above the ground is Sonny's line of sight?
approximately 124.6 feet
approximately 156.4 feet
approximately 224.6 feet
approximately 293.3 feet

Answer:
630 square meters.
Step-by-step explanation:
Given:
A triangular prism has an equilateral triangle base whose sides are 6 meters. The height of the prism is 35 meters, and the height of the base is 5.2 meters.
<u>Question asked:</u>
What is the lateral surface area of the prism?
<u>Solution</u>:
As we know:
Perimeter of the equilateral triangle base = 6 + 6 + 6 = 18 meters
The height of the prism = 35 meters
Lateral surface area of the prism = 18 35 = 630 square meters.
Thus, lateral surface area of the prism is 630 square meters.
