Alifeguard is 12.5 ft above a pool in her lifeguard station when she spots a swimmer struggling 42.3 ft away from the base of her station. what is the angle of depression from the lifeguard station to the swimmer? round the answer to the nearest hundredth. a. 2.49 b. 12.56 c. 16.46 d. 20.24

tan(angle) = opposite leg / adjacent leg

tan(angle) = 42.3 / 12.5

angle = arctan(42.3 / 12.5)

angle = 73.54

Angle of depression = 90 - 73.54 = 16.46 degrees.

The answer is C.

c

step-by-step explanation:

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
