a kite with a string 150 feet long makes an angle 45 with the ground, assuming the string is straight ,how high is the kite?

since a 45 degree right triangle has two equal sides, using pythagorean theorem,
150^2 = a^2 + a^2
2a^2 = 150^2
a = squareroot(150^2/2) = 75sqrt(2) feet = ~106.066 feet
sin45 = h/150
h = 150*sin45 =
