Question

Luke is programming a video game in which the rocket is to move 5 units at an angle of 25 degrees with the horizontal. How long is his Move x (to the nearest 0.1 unit)? How long is the "Move Y (to the nearest 0.1 unit) According to Occupational Health and Safety Standards (OSHA), safe ladder usage requires the following guidelines: Place the ladder base at a 1: 4 ratio from the vertical horizontal vertical). For every 4 feet of working length the base of ladder should be 1 foot out from the top support Using the safety guidelines, what angle should all ladders make with the ground? How long is the ladder if you want it to reach 20 feet up the wall?

Explanation / Answer

7. cos theta=adjacent/hypotenuse

cos 20 =move x/5

move x=5 cos 20= 4.7

sin theta= opposite/hypotenuse

sin 20= move y/5

move y=5 sin 20=1.7units
