Question

Spiderman is standing 79 feet from the base of a building that is on fire. From an

angle of elevation of 630, he sees a woman screaming for help. How long must he
shoot a web-line in order to rescue the woman?
A) 88.66 feet
CB) 174.01 feet
C) 155.05 feet
D) 35.87 feet

Answer 1

B) 174.01 feet

Explanation:

The relevant trig relation is ...

Cos = Adjacent/Hypotenuse

cos(63°) = (79 ft)/(web length) . . . . . substitute given values

Solving for web length, we have ...

web length = (79 ft)/cos(63°) ≈ 174.01 ft

His web line must be 174.01 ft long.
