Great work today everyone! I loved seeing you all working hard and helping each other out! Keep it up!
Tomorrow we'll start a new section, 4.2--and start learning about the unit circle!
And don't forget--test Friday!
Here's your homework in case you lost it (or were out)!
Directions: Each question is worth 3 points: 1 point for
drawing the correct picture, 1 point for setting up an equation using the proper
trigonometric function, and 2 points for finding the correct answer (with
units!!!!). In your picture you should label the given sides/angles, and
unknown sides/angles. Good Luck!
1. A boy flying a kite lets out 300 feet of string which makes an
angle of 38 with the ground. Assuming that the string is straight, how high
above the ground is the kite?
2. A straight road to the top of a hill is 2500 feet long and has
a 12
angle
of elevation. Find the height of the hill.
3. A 25-foot ladder leans against a building. The ladder’s base is
13.5 feet from the building. Find the angle which the ladder makes with the
ground.
4. During one of your many snow days, you built a ramp to sled off
of. The ramp is 10 feet long and 3 feet high. What is the angle of elevation of
the ramp?
