Answer:
The height of the kite is 7.5 feet.
Step-by-step explanation:
If the kite has an 11 ft line attached to it and it casts an 8 feet shadow, we will have a rectangle triangle (see picture below).
To find the height x of the kite, we can apply the Pythagorean theorem.
x² = 11² - 8²
x² = 121 - 64
x² = 57
x =√57
x = 7.54
x = 7.5
Therefore, the height of the kite is 7.5 feet.
The line, shadow and the height form a right angled triangle so we can apply the Pythagoras theorem here:-

Answer:
12
Step-by-step explanation:
Use the Pythagorean theorem which is a^2 + b^2 = c^2
c is hypotenuse and a and b are the legs
we need to find a^2 so
a^2 + 16^2 = 20^2
a^22 + 256 = 400
then subtract 256 from 400
a^2 = 144
square root 144
= 12
