Answer: Second option is correct.
Step-by-step explanation:
A company wants to try out two new toothpaste brands (brand A and brand B) on customers who use the company's existing toothpaste brand.
So, the best method for this study is an experiment.
As the company will try its two new brands who are already using their existing toothpaste brand.
They will get to know their like and dislike about their two new toothpaste brands.
Hence, Second option is correct.
Refer to the attached diagram for help.
All radii of a circle are congruent.
Tangent segs LP and LQ are congruent. (Tangent segs drawn to a circle from the same point are congruent)
Because of this we can establish OPLQ as a kite.
OPLQ is a kite implies that OL bis. angle PLQ.
An angle bis. divides an angle into 2 congruent, parts, so angle OLP must be 30 degrees.
Since tangents form right angles with the radius, angle OPL is right.
Now we have a right triangle OPL with a 30-degree angle. The other angle must be 60 degrees because of the no-choice theorem. (180-(30+90)) = 60
We know that OP is 6 because it is a radius of circle O. How do we use that to find OL? Well, we <em>could</em> use trig, but you might recognize this as a special triangle!
The side opposite the 30 degree angle = x
The side opposite the right angle = 2x
So OL must be 12!
