Well, the sum of the angles in a triangle equals 180 degrees.
So you do 180 minus the two angles to get the third angle.
180 - 78.4 - 57.2 = 44.4
44.4 degrees
To find AC, use the law of sines.
Length A / sin (angle a) = length b / sin(angle b)

What are the options? Note that "and" means multiply and "or" means addition
(2 democrats and 3 republicans) OR (3 democrats and 2 republicans)

Answer:
Time, t = 2 seconds
Step-by-step explanation:
The height of a flare fired from a 32-foot high platform can be modeled by the function :

Here, h is the height in feet above the ground and t is the time in seconds.
It is required to find the time taken by the flare to reach the ground. When its reaches ground, height covered by it equals 0 such that,
h = 0

Neglecting t = -1 seconds, the time taken by the flare to reach the ground is 2 seconds.
