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
I believe the answer would be 8 because jack will not move
(1/8)x + 2 = 9 yields a solution of 56.
(1/9)x – 8 = 7 and (1/9)x – 7 = 8 both have a solution of 135.
Answer:
3rd option
Step-by-step explanation:
use hypotenuse method
Answer:
the first one is negative
Step-by-step explanation:
1= -168
2= 360
3= 0
4= 360
a negative times a negative is a positive, 1 has 3 negatives tho so its gonna be a negative. 3 would be the other one but it has a zero making the answer 0
