Question

So, I need help with the following three:

1. A ladder 7 m long stands on level ground and make a 73 degree angle with the ground as it rests against a wall. How far from the wall is the base of the ladder?

2. To see the top of a building 1000 feet away, you look up 24 degrees from the horizontal. What is the height of the building?

3. A guy wire is anchored 12 feet from the base of a pole. The wire makes a 58 degree angle with the ground. How long is the wire?

Answer 1

Okay, so I got 2 for the first one, 445 for the second, and 19 for the third.
