Question

Jennifer is flying her kite and it gets stuck in a tree. She knows the string on her kite is 15 feet long and she is 4 feet from the tree.how long of a ladder (in feet ) will she need to get her kite out of the tree? enter your answer as a decimal rounded to two decimal places.

Answer 1

15.52feet

Step-by-step explanation:

To get the length of the lader, we will use the pythagoras theorem;

Taking length of the string as the opposite and the distance of Jenifer from the tree as adjacent

Given

length of kite = 15feet

Distance of Jenifer from the tree = 4feet

Required

Length of thr ladder L

Using pythagoras theorem;

L^2 = 15^2 + 4^2

L^2 = 225 + 16

L^2 = 241

L = \sqrt{241}

L = 15.52 feet

Hence the length of the kite to two decimal places is 15.52feet
