Explanation:
Given that a triangular prism is 20 yards long and has a triangular face with a base of 24 yards and a height of 16 yards . the other two sides of the triangle are each 20 yards.
<u>Surface area of the triangular prism:</u>
The formula to determine the surface area of the triangular prism is

where base
,
height
,
length
and
Perimeter 
Substituting these values in the above formula, we get,



Thus, the surface area of the triangular prism is 1664 square yards.
The answer is (-7, -12).
Attached is the graph to show the answer.
Answer:
switchy switchy
Step-by-step explanation:
sin 15 = 38/x
We need to switch the sin15 and the x by multiplying both sides by x and dividing both sides by sin 15
x = 38/sin 15
