The hole for a support needs to be 5 feet deep. It is currently 1 foot and 9 inches deep. How much deeper must the hole​ be

3 foot 3 inches

Step-by-step explanation:

How much deeper the hole should be = intended depth - current depth

Convert feet to inches for easy calculation

1 ft = 12 inch

5 x 12 = 60 inches

1 foot = 12

12 + 9 = 21 inches

60 - 21 = 39 inches

convert inches to feet

39 /12 = 3 feet 3 inches

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
