> ** The kite that Jalien is flying is at an 65º angle in aspects of Jalien to the top of the kite. The the kite from the ground is a measurement of 11ft. The angle made from the ground to the start of the kite where Jalien is holding is a 70º angle. What is the length of the kite from Jalien? Use sine to solve for the horizontal distance of Jalien to the kite. ** > >  >

> ** Karl is building a square pin for his rabbits. The side of the square is 2 ft. If Karl wants to build a diagonal gate inside of the square to separate the female and male rabbits from each other, how long does the gate have to be?
