Akite, flying 50 feet high in the air is attached by a string to a stake in the sand. how long is the string to the nearest tenth of a foot?

a) 50.0 feet
b) 70.7 feet
c) 86.6 feet
d) 100.0 feet

Height of the kite from the ground = 50 feet
Angle at which the kite is flying = 45 degrees
Let us assume the length of the string = x feet
Then
x = 50 * (square root 2)
   = 50 * 1.414
   = 70.7 feet
From the above deduction, it can be concluded that the correct option among all the options that are given in the question is the second option or option "b". 

If im correct the answers should be 5 am and 28 chores
