Step-by-step explanation:
Define a cyclic quadrilateral by a quadrilateral that is circumscribed by a circle. In this case, since the quadrilateral shown is circumscribed by a circle, it is a cyclic quadrilateral.
A property of all cyclic quadrilaterals is that their opposite angles are supplementary, meaning they add up to 180 degrees. Since 
and 
are opposite angles in the quadrilateral, they must be supplementary. Therefore, we have the equation:
Answer:
ABOUT 13 PERCENT

I AM NOT CERTAIN BUT I GOT IT BY:
NEW PRICE - OLD PRICE divided by OLD PRICE X 100
Answer:
Both of them can be simplified.
Recall that 4 = 2^2.
2^7 / 4^2 = 2^7 / (2^2)^2 = 2^7 / 2^4 = 2^(7-4) = 2^3 = 8
Similarly, 2^7 / 2^4 = 2^(7-4) = 2^3 = 8
The answers to both exercises are 8.
Answer:
Step-by-step explanation:
Volume of sphere = 4/3 *pi * r^3
= 4/3 * 3.14 * 52
= 523.33
