Question

Kari is flying a kite.she realeses 50feet of string.what is the approximate difference in the height of the kite when the string makes a 25 degree angle with the ground and when the string makes a 45 degree angle with the ground?round to the nearest tenth

Answer 1

sinα=h/s

h=ssinα

h=50sinα

dh=h(45)-h(25)

dh=50(sin45-sin25) feet

dh≈14.2 ft (to nearest tenth of a foot)
