Answer:

centre = (0, 0 ), radius = 5

Step-by-step explanation:

The equation of a circle centred at the origin is

x² + y² = r² ( r is the radius )

x² + y² = 25 ← is in this form

with centre = (0, 0 ) and r = \sqrt{25} = 5

What is the answer to this​
zubka84 [21]

Answer: C. 124

Step-by-step explanation:

In parallelograms, any two consecutive interior angles add to 180 degrees. CDA and BCD are consecutive interior angles. Since the measure of angle CDA is 56 and the sum of CDA and BCD equal 180, then to find the value of BCD, evaluate 180-56.

180 - 56 = 124

Solve for y please!!!!!!!!!!!!
sergij07 [2.7K]

Answer:

y=3r-230

Step-by-step explanation:

Subtract the 3r from the first aide to put it along with the 230. Then, we must divide both sides by negative 1 to get y by itself. This gives us y=3r-230.
