Hello!


The standard equation of a circle is x² + y² = r², when the center is at the origin.


So therefore, we just need to substitute the radius into the equation to find the appropriate equation.


x² + y² = (3)²

x² + y² = 9


Therefore, the equation of the circle is C, x² + y² = 9.

Find the value of each variable. What are x and y ?
hram777 [196]

Answer:

Step-by-step explanation:

since 105 + z is a straight line we know it equals 180 so we can use this equation

180 = 105 + z

simplify

75 = z

the since we know that all quadrilaterals equal 360 degrees we can add our two given number and z then subtract from 360:

102 + 85 + 75

= 262

now subtract

360 - 262

= 98

y = 98

hope this helps <3
