Please help me, I really need it! Determine the length of a ladder needed to reach the roof of the building shown below. The building is 13 feet tall and when the ladder leans against the angle created at the peak is 42°. In order to reach the roof of the building, what should be the length of the ladder?

answer: 457.14

step-by-step explanation:

205 - 45 = 160

160 / .35 = 457.142857

15 batches are the most you can make

step-by-step explanation:

is there supposed to be a diagram or a graph for this one? ?

step-by-step explanation:

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
