Since the sum of the angles of a triangle = 180°

Then  <span>80º + (2x + 2)º + 5xº  = 180</span>°
                          82° + (7x)° = 180°
                                    (7x)° = 180° - 82°
                                        x   =  98° ÷ 7
                                    ∴  x   = 14

Reem earns $16 per hour for the first 8 hours of her shift. For each additional hour she works beyond the first 8 hours, she ear
RideAnS [48]

The single shift worked by Reem is 16 hours long.

Total earned = $320

First 8 hours (earning per hour) = $16

Additional hours = $24 per hour

Let the total number of hours worked = m

The Number of hours after 8 hours = m - 8

Representing the scenario with an equation :

(16 × 8) + (24 × (m - 8)) = 320

128 + 24m - 192 = 320

-64 + 24m = 320

24m = 320 + 64

24m = 384

Divide through by 24

m = 384 / 24

m = 16

Hence, the shift is 16 hours long.
