Document Summary

Side c is 10 m and side b is 6 m. To determine the length of side a, use pythagorean"s theorem (c2 = a2 + b2) a2 = 102 62 a. Side a is 8 m and side c is 10 m. For a right triangle, the ratio of the opposite side to the hypotenuse is the sin of the angle. Side b is 10 m and side c is 6 m. angle a is 25 degrees. Solution: use the cosine law: c2 = a2 + b2 -2abcos(c) Side a is 5 m and side c is 8 m. angle a is 30 degrees. Solution: either from pythagorean"s rule or recognizing that both bc and cd are the hypotenuse of a 3- 4-5 triangle, the length bc is 5 in, and cd is 7. 5 in (cd is a 3-4-5 triangle with multiples of.
