Answer: w + y = 180 degrees
Step-by-step explanation: The opposite angles in a cyclic quadrilateral are supplementary.
Answer:

Step-by-step explanation:
Given
The above diagram


Required
Determine length AB
Tangents drawn from the same point of a circle are equal;
<em>This implies that</em>

Substitute values for AB and AC

Subtract 3y from both sides


Divide both sides by 8



Substitute
for y in 




1. a=h(b+c)
2. distribute the h:
a=hb+hc
3. move the 'hb' to the left:
a - hb = hc
4. subtract the a from both sides:
-hb = hc - a
5. divide both sides by -h to isolate b:
b = -hc+a/h
