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.
B=22.62
16/sin30=b/sin45
16sin45/sin30 =22.62
A=a+b/2 (h) is the equation.
Answer:
34 feet
Step-by-step explanation:
let length of ladder be x
x = 32.131083564
