Evaluation Criteria for Assignments 1. Is the solution method presented in a way that makes it easy for someone else to understand
the steps in mathematical thinking involved?
2. Are the variables used in a problem defined explicitly?
3. Are diagrams, charts and/or tables included? Are they carefully and clearly labeled?
4. Is there evidence of coherent mathematical thinking? Are there connections made to material
learned in the course?
5. Is the solution accurate?

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

answer is 33
