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.
Answer:
the equivalent ratios of 6 and 5 is D.
Not an equation for those 2 points, but rather "the equation of the line thru (4,6) and (-4,0).
6 - 0
Slope? m = ----------- = 6/8 = 3/4
4 -(-4)
Equation? Start with y = mx + b. Then 6 = (3/4)(4) + b, or 6 = 3 + b. b = 3.
The desired equation is y = (3/4)x + 3.
