Adrawbridge will sometimes open up to let boats and other water traffic pass through. as it opens, the surface of the drawbridge raises above the level of the roadway, as modeled by the function: if the length of the drawbridge, r, is 18 meters, and the point p is 7 meters above the roadway, what is the distance d?

The distance d is 16.583 meters ( approx )

Step-by-step explanation:

Here, r represents the length of the drawbridge, p represents the point above the roadway and d represents the distance d,

Let h be the distance of point P above the roadway,

Hence, the function that shows the given situation,

Here, r = 18 meters, h = 7 meters,

Thus, The distance d is 16.583 meters ( approx )

35/2 is it i think maybe

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough
