Quadrilateral OPQR is inscribed in circle N, as shown below. Which of the following could be used to calculate the measure of ∠ROP?

A:(6x − 4)° + (2x + 16)° = 360°
B: (x + 16)° + (6x − 4)° = 360°
C: (6x − 4)° + (2x + 16)° = 180°
D: (x + 16)° + (6x − 4)° = 180°

1. a parachutist is 800 feet above the ground when she opens her parachute. she then falls at a constant rate of 5 feet per second. select the equation that represents this situation. h = -800t + 5 y = -5x + 800 h = 5t - 800 y = 800x + 5 i need
