For problems 14 and 15, a drain pipe is to be laid between 2 points. One point is 15 feet higher in elevation than the other. The pipe is to slope at an angle of 12° with
the horizontal.
Find the length of the drain pipe. Round to 2 decimal
places.

Length of the drain pipe is 72.15 feet.

Step-by-step explanation:

From the figure attached,

A drain pipe is to be laid between two pints P and Q.

Point P is 15 ft higher than the other point Q.

Angle of elevation of point P from point Q is 12°.

Let the length of pipe is l feet.

By applying Sine rule in the given right triangle PRQ,

Sin(∠Q) =

Sin(12) =

0.20791 =

l = 72.15 ft

Therefore, length of the drain pipe is 72.15 feet.
