Answer:
x = 1
Step-by-step explanation:
x 1
-------- = ----
x + 1 2
Begin the solution by multiplying both sides by the LCD, which is 2(x + 1):
2x = 2(x + 1)/2, or
2x = x + 1, or
x = 1
1
Check: is -------- = 1/2?
1 + 1
YES
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.
