Use the unit circle to find csc 270°

Step-by-step explanation:

We want to find the value of .

Recall from the reciprocals of trigonometric ratios that;

Note that; 270 degrees is a quadrantal angle. It makes an angle of 90 degrees with the positive x-axis and it is in the third quadrant

This implies that;

On the unit circle,

This implies that;

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.

the answer is b
