In this case, the ladder formed a triangle with the wall, you can see it in the attached diagram.
Let the distance of ladder from base of wall = x
Now to find the value of x, we use cosine ratio.
cos ∅= Adjacent / Hypotenuse
Put values
cos72= x/15
15 cos 72 = x
or
x=15 cos 72
x=4.6 ft ( Rounded to nearest tenth)
So, the distance of ladder from base of the wall is 4.6 ft.
X = 63 because they are complementary angles same degree! :) please mark brainliest

Step-by-step explanation:
the first point where lines intersect is at 2,3 meaning at 1 it is 1.5 meaning 1500 points
