1) Because
is a central angle,
.
Since
and
are supplementary, they form a linear pair, and thus 
5) Tangents drawn from an external common point are congruent, so CR=CP=8 and RB=BQ=4. This means that QA=11, and so PA=11 as well. Adding CP+PA, we get AC=19.
6) By the inscribed angle theorem, angle QPR measures 36 degrees.
Answer: The answer would be
75
Step-by-step explanation:
If you do 75+75+30 it would add up to 180 which is what a triangle is worth.
Answer:
Hi there!
The simplified version is:
18x-20
Step-by-step explanation:
2(4x-6) -8 +10x
First, multiply the 2 by the parentheses.
8x -12 -8 +10x
Next, combine like terms
18x -20
This is the simplified version!
Hope this helps
The answer is choice D. All coplanar points equidistant from a given point.
In other words, all points that arethe same distance away from a fixed point. For example, if you have some fence post and you are 2 feet away from the fencepost, then that marks one point on the circle. Then move to another point that is also 2 feet away from the fencepost. Repeat until you have a bunch of points. All of these points will form a circle. The term "coplanar" means "all in the same plane". A plane is a flat surface like a flat piece of paper that doesn't bend or curve.
Perimeter=sum of all 3 sides
