Answer:

(x - 5) ^2 + (y -2)^2 = 1

Step-by-step explanation:

This is for a circle.

We need to complete the square

(x^2 -10x ) + ( y^2 -4y ) = -28

(x^2 - 10x +25) + (y^2 - 4y 2y) = -28 + 25 + 4

(x-5)^2 + (y-2)^2 = 1

The center of this circle would be (5,2) with a radius of 1.

The answer is 25 degrees.

This is how you solve the equation, first you must know that the straight like ABC=180, DBC is 130, so the remaining amount is 50 degrees, BE is a bisector of ABD which means it splits ABD right down the middle. So ABE+EBD=50 degrees, 25+25=50 since both sides MUST be equal in order for BE to be a bisector of ABD.

36/48 in simplest form

babunello [35]

Well you can simplify them by dividing by there greatest common factor.
In this case they can both divide by 12!
Thats the biggest number they can divide by...
Soo..
36 ÷ 12 = 3
----------------
48 ÷ 12 = 4

So your answer is 3/4!

Good Luck! :)
