The height of the kite is 4.89 feet

Explanation

The length of the line attached to the kite=7 feet

The length of the shadow that is cast on the ground=5 feet

the system forms a right angled triangle where the taught string of the kite is the hypotenuse, the shadow is the base and the height of the kite above the ground is the height.

H=7 feet

b=5 feet

using pythagoras theorem

h^2+b^2=H^2\\h^2=H^2-b^2\\h^2=7^2-5^2\\=49-25\\=24\\h=\sqrt{24\\} =2\sqrt{6} \\=4.89 feet

The kite is 4.89 feet above the ground

925 round to the nearest hundred
yarga [219]
925 rounded to the nearest hundred is 900 becuase first we identify the hundreds digit which in this case is 9. Second,we identify the next smallest place value (the digit to the right of the hundreds place) which in this case is 2. Is that digit greater than or equal to five? No - we round Down. The hundreds digit is stays the same but every digit after it becomes a zero.
