Answer:

Step-by-step explanation:

All angles in a triangle must add up to 180 degrees. If you know 2 angles, you must know the last one by subtracting the other two from 180. If you subtract 50 and 28, the two known angles in this situation, from 180, you get 102. Therefor, the last angle must be 102 degrees, or choice C.

Can you solve this? It is for MATH 111

The equation only is true for objects with negligible air resistance. A feather does not have this property.
Using the equation shown:
50 = -16t^2
t^2 = 50/16 = 3.125
t = sqrt(3.125) = 1.77 seconds
