Jack and Jill got tired of falling down that hill with a pail of water and decided to try flying a kite instead. Jack is holding the kite string, and Jill is standing directly under the kite. The kite string forms a 61° angle with the line of sight between Jack and Jill, who are the same height. The two BFFs are standing 12 yards apart. How long is the kite string?

Rhys · Answer 1

Because Jill is standing directly under the kite the angle between jack Jill and the kite is 90°

so

a=12 yards

A°=61°

B°=90°

b=?

to find b we have a formula:

a devided by the sinus of A equals b devided by the sinus of B

12:sin (61°) = b:sin (90°)

12:0.8=b:1

15=b
