4x - 3y = 22 ⇒  4x - 3y = 22 ⇒ 4x - 3y = 22
2x  -  y = 10 ⇒2(2x - y) = 10 ⇒ <u>4x - 2y = 10</u>
                                                          5y = 32
                                                          <u>5y</u> = <u>32
</u>                                                           5      5<u>
</u>                                                            y = 6.4
                                              4x - 3(6.4) = 22
                                                4x - 19.2 = 22
                                                <u>     + 19.2 + 19.2
</u>                                                            4x = 41.2
                                                           <u>4x</u> = <u>19.2</u>
                                                            4        4
                                                             x = 4.8
                                                        (x, y) = (4.8, 6.4)

Given the following diagram, find the measures of ZA and ZB.
Nutka1998 [239]

Answer:

x = 14.6

ZA = 30.8

ZB = 33.2

Step-by-step explanation:

First, solve x: (knowing all angles of a triangle are 180º)

116º + (2x + 4)º + (3x-13)º = 180º

116 + 2x + 4 + 3x - 13 = 180

2x + 3x = 180 + 13 - 4 - 116

5x = 73

x = 73/5 = 14.6

ZA = 3*14.6 - 13 = 30.8

ZB = 2*14.6 + 4 =33.2

Test:

116º + 33.2º + 30.8º = 180º
