Question 764289: Sandy stops to check on tom, who is on a ladder recovering a frisbee from the roof. When tom talks to sandy, who is standing 25 feet from the house, the angle of depression is 50 degrees.
1. From Sandy's perspective, what is the angle of elevation?
2. How far above the ground is Tom? (round to the nearest hundredth)
3. How far up the ladder has Tom climbed? (round to the nearest hundredth here, too.)
4. For safest use of a ladder, the recommended angle is 75 degrees ( as formed by the ladder and the ground.) Is tom using the ladder safely (within 2 degrees of recommendation)? Show your calculations.
5. Use identities and definitions to show that cos 0=sin 0 cot 0 Answer by solver91311(24713) (Show Source):
