This seems like a simple conversion problem. 1m=?cm and 1cm=?m.
Since this uses the metric system, you know the general layout of the prefixes: K H D M d c m. I remember this as King Henry died Monday drinking chocolate milk, but as long as you remember it you're good.
Let's look at 1m. Centimeters is two places away from it
K H D (M) d (c) m
This means you move the decimal place to the right two times, so 1 meter is equal to 100 centimeters.
For 1 cm, the meter position is two places away. This means we have to move the decimal place to the left two times. So, 1 centimeter is equal to 0.01 meters.
Answer:
7.878 ft far
Step-by-step explanation:
Given:
- A ramp is to be lifted to an angle Q = 10 degrees
- The total length of the ramp L = 8 ft
Find:
- how far does the ramp need to be away to hit the edge of the step
Solution:
- The question asks in "other words" the horizontal distance (d) from the ramp pivot on the floor to the edge of the step when it is lifted 10 degrees.
- We will use trigonometry to solve a right angle triangle: The horizontal distance is a projection of Length L on to the flat ground surface. Hence, we have:
cos(Q) = d / L
d = L*cos(Q)
- Plug in values:
d = 8*cos(10)
Answer: d = 7.878 ft
