Question 536494
The string of the kite forms the hypotenuse
of a right triangle with 200 ft as the base
Call {{{h}}} the height of the triangle
Use the Pythagorean theorem
{{{ 250^2 = 200^2 + h^2 }}}
{{{ h^2 = 250^2 - 200^2 }}}
{{{ h = sqrt( 250^2 - 200^2 ) }}}
{{{ h = sqrt( 62500 - 40000 ) }}}
{{{ h = sqrt( 22500 ) }}}
{{{ h = 150 }}}
The kite is 150 ft above the water
