Artie's dad's house is 21 ft tall. if artie's dad is at the top of the house installing shingles, and his son artie is on the ground 12 ft away from the base of his dad's house, what is the angle of depression from the top of the house to the spot where artie is standing?
a. 46.56
b. 60.26
c. 161.62
d. 11.65

B) 60.26 degrees

Step-by-step explanation:

The above picture might help you to visualise the problem better. Moreover, do also note that the angle of depression is calculated from the horizontal. Let a be the angle of depression.

tan a = opposite / adjacent

tan a = 21 / 12

a = tan inverse (21/12)

a = 60.26 degrees

Hence angle of depression is B) 60.26 degrees

the correct answer is d
