Think of sea level as 0 on number line
-13 + 6 - 15
The answer is a I believe
Multiply all the numbers and that would be your answer
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.
Step-by-step explanation:
