- She realized that she needed to use the Law of Sines. So she came up with this equation. 10 / sin 500 = x / sin 700. She then cross multiplied and got this equation. x = 10 sin 700 / sin 500. She then plugged this equation into her calculator. She found that x = 12.3. So she has the through the bag 12.3 feet.
- Jane was walking home when she ran into her young friend Maggie.
