Use SOHCAHTOA and set up a ratio such as sin(16) = 14/x. (From here solve for X). By the way, you could also use cosine. Method 2. Set up the following equation using the Pythagorean theorem: x 2 = 48 2 + 14 2. (From here solve

Cosine: For a right triangle the cosine of an angle is related by the adjacent side divided by the hypotenuse. For a right triangle to solve for the horizontal length use the angle from the

We know angle C = 37º, and sides a = 8 and b = 11. The Law of Cosines says: c2 = a2 + b2 − 2ab cos (C) Put in the values we know: c2 = 82 + 112 − 2 × 8 × 11 × cos (37º) Do some calculations:
