Answer:

  • Sin A = \frac{opposite}{hypotenuse} =\frac{32}{40} =\frac{4(8)}{5(8)} =\frac{4}{5}
  • Cos C = \frac{adjacent}{hypotenuse} =\frac{16}{34}=\frac{2(8)}{2(17)} =\frac{8}{17}
  • Tan A = \frac{opposite}{adjacent} =\frac{21}{20}

-14x + 15y = 15 <br> -21x - 20y = -10<br> Use substitution to find the x and y coordinates.
denis-greek [22]
                  -14x + 15y = 15
        -14x + 14x + 15y = 14x + 15
                             15y = 14x + 15
                              15           15
                                 y = ¹⁴/₁₅x + 1
                   -21x - 20y = -10
     -21x - 20(¹⁴/₁₅x + 1) = -10
-21x - 20(¹⁴/₁₅x) - 20(1) = -10
         -21x - 18²/₃x - 20 = -10
                  -39²/₃x - 20 = -10
                            + 20  + 20
                          -39²/₃x = 10
                           -39²/₃   -39²/₃
                                   x = ⁻³⁰/₁₁₉
                                   y = ¹⁴/₁₅x + 1
                                   y = ¹⁴/₁₅(⁻³⁰/₁₁₉) + 1
                                   y = ⁻²⁸/₁₁₉ + 1
                                   y = ⁹¹/₁₁₉
                              (x, y) = (⁻³⁰/₁₁₉, ⁹¹/₁₁₉)
