k you.

1)
The bisector is the midpoint of the curved line. To find it, place the compass at point A. Open it and draw an arc on both sides.
Without altering the compass, place it at point B and draw arcs on both sides to intersect the previous arcs.
Mark the two points of intersection. Draw a line touching both points. The point where the line touches line AB is the bisector
The sample is shown below
Point C is the bisector

Answer:
Step-by-step explanation:
You need 2 things in order to solve this equation: a trig identity sheet and a unit circle.
You will find when you look on your trig identity sheet that
so we will make that replacement, getting everything in terms of sin:
Now we will get everything on one side of the equals sign, set it equal to 0, and solve it:
We can factor out the sin(theta), since it's common in both terms:
Because of the Zero Product Property, either
or
Look at the unit circle and find which values of theta have a sin ratio of 0 in the interval from 0 to 2pi. They are:
The next equation needs to first be solved for sin(theta):
so
and
Go back to your unit circle and find the values of theta where the sin is -1/2 in the interval. They are:
