Answer:

The correct answer is D. 69

Step-by-step explanation:

Let's recall that if an exterior angle has its vertex where two rays share an endpoint outside a circle, the measure of that exterior angle is found by dividing the difference between the measures of the intercepted arcs by two.

Therefore, we have:

x = (Measure of arch CD - Measure of arch BD)/2

Replacing with the real values:

x = (210 - 72)/2

x = 138/2 = 69°

The correct answer is D. 69

Answer: 5.5 seconds

Since the penny is dropped and not thrown, the initial velocity is 0 and the initial height is given as 150m. Plugging these into the given equation result in $-4.9t^2+0t+150=-4.9t^2+150$ . To find how long it will take for the penny to hit the ground we set the equation equal to zero and solve for t. Since this doesn't factor, you'll need to use the quadratic formula:

$+/-\frac{\sqrt{0^2-4(-49)(150)}}{2(-49)} =+/-\frac{10\sqrt{15} }{7}=+/-5.533$ . Since time cannot be negative, the answer will be the positive 5.5 seconds.
