You can make a proportion out of this.
(2.4/3) = (x/8)
Solve for x.
If you are to use trig, then
cos angle = 2.4/3, solve for angle.
and cos angle = x/8
solve for x.
(2.4/3) = (x/8)
Solve for x.
If you are to use trig, then
cos angle = 2.4/3, solve for angle.
and cos angle = x/8
solve for x.
thank you
Two ladders are leaning at the same angle against a vertical wall.
The shorter ladder is 3 m long and it reaches 2.4 m up the wall.
The longer ladder is 8 m long.
How much farther up the wall does the 8 m ladder reach?
