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

Rama09 [41]

Answer:

$m \angle PQR=80^{\circ}$

Step-by-step explanation:

Missing figure drawn.

The measure of ∠PQR is found by the property of inscribed quadrilateral. In an inscribed quadrilateral the opposite angles are supplementary:

$\left\{\begin{matrix}\angle O+\angle Q=180^{\circ} & \\ \angle P +\angle R=180^{\circ} & \end{matrix}\right.$

$x+16+6x-4=180^{\circ}\\7x+12=180\\7x+12-12=180-12\\7x=168\\\frac{7x}{7}=\frac{168}{7}\\x=14\\\angle Q=6(14)-4\Rightarrow m\angle Q=84-4\Rightarrow Q=80^{\circ}$

Two cyclists, 55 miles apart, start riding toward each other at the same time. One cycles 5 miles per hour faster than the other

tangare [24]

Answer:

r = 6 mph and f = 11 mph

Step-by-step explanation:

Representations:

1) speed of faster cyclist: f = r + 5

2) speed of slower cyclist: r

Distances covered:

(r + 5)(5 hr) + r(5) = 55 mi (total distance covered)

Then 5r + 25 + 5r = 55, or, after reducing this equation:

r + 5 + r = 11, or

2r = 6

Then r = 6 mph and f = 11 mph
