CHAPTER 9 PRACTICE TEST

As a study aid, we have included complete solutions for each Practice Test problem at the end of this book.

In all triangle solutions, sides a, b, c, are opposite angles A, B, C, respectively.

  1. By use of a diagram, find the vector sum 2A + B for the given vectors.

    Vector Ay points up and right. Vector B points up and left.

  2. For the triangle in which a = 22.5 , B = 78.6 °  ,  and c = 30.9 ,  find b.

  3. A surveyor locates a tree 36.50 m to the northeast of a set position. The tree is 21.38 m north of a utility pole. What is the displacement of the utility pole from the set position?

  4. For the triangle in which A = 18.9 °  , B = 104.2 °  ,  and a = 426 ,  find c.

  5. Solve the triangle in ...
