First set up a right triangle:
/)
H / ) X (wall)
/ )
/75____)
4 (distance from ladder to wall)
ladder=H
distance from ladder to wall=4
height of wall=X
We know that the ladder and the ground make a right triangle so we can use trig functions to solve.
since tan is opposite side over adjacent side we have this so far:
tan75=X/4
4tan75=X (multiply both side by 4)
type that into your calculator and you should get about 15 feet.
Does this answer your question?
A ladder leaning against a vertical wall makes a angle of 75degree with the ground. If the foot of the ladder is 4 feet from the base of the wall, would this ladder be long enough for you to retrieve the suction dart that your friend stuck 17ft up the wall?

sorry I tried to make a diagram up there but it turned into jibberish when I posted.
Also I forgot to put that the angle between the ladder and the ground is 75.

9. An equilateral triangle has an altitude length of 36 feet. Determine the length of a side of the triangle.
a 12-foot ladder rests against the side of a house.the base of the ladder is 3 feet away from the side of the house.how high above the ground is the top of the ladder? round to the nearest of a foot
The base of a ladder should be placed 3 feet from the wall for every 5 feet of ladder length. How many a ladder is needed to safely reach 36 feet above ground?
