Answer:
X + Y - W - Z = 180
Step-by-step explanation:
In parallel lines If you use the rules of:
* Alternate angles are equal
* Linear Pair Angles supplement to 180
And use the picture below for calculating the result: finally we get
Z = Y - (180 - (X - W)) which becomes the answer above if you simplify the parentheses.

Step-by-step explanation:
It is given that,
Central angle
Arc length = 33 cm
Formula for arc length :
where, s is arc length, r is radius and is central angle in radian.
Substitute s=33 and in the above formula.
Multiply both sides by 10.
Divide both sides by .
Put
Therefore, the radius of the circle is 15 cm.
