Answer:
Step-by-step explanation:
-4 = 5 + f....we want to isolate f, so subtract 5 from both sides
-4 - 5 = 5 - 5 + f
-9 = f <===
The angle of elevation is 26.565 (3dp)
let h be the end height of the ramp above
the ground , l be the length of the ramp and
the angle of elevation is (30)
i'm not sure, sorry
2y+4=3(y-1)
2y+4=3y-3
4+3=3y-2y
Y=7
X=2
9/10 * 5/2 = 45/20
The quotient will be greater than 1
