Answer:
Explained below
Step-by-step explanation:
If two angles are congruent, it means that they have the same angle whether in degrees or radians.
Now, angles are said to be congruent so as long as the measure of the angles are the same and regardless of them point in the same or different directions.
They must not necessarily be made with lines having the same length.
For example, in the diagram of the 2 triangles I've attached, angle C and Z are congruent, and they are both marked accordingly by one short curved line. Similarly angle A and B are congruent and they are both marked accordingly by two short lines.

Answer:
1) Factor form :
2) 8 second after launch.
Step-by-step explanation:
The height of the ball (in meters above the ground) t seconds after launch is modeled by
To find the time when ball hit the ground, we need to find the factor form of the given function.
When ball hi the ground, then height of the ball from the ground is 0.
Using zero product property, we get
Ball hit the ground at t=0 and t=8. It means ball hit the ground in starting and 8 second after launch.
