Urgent will give brainliest determine two pairs of polar coordinates for the point (5, 5) with 0° ≤ θ < 360°.

(5sqrt(2), 45 deg)

(-5sqrt(2), 225 deg)

Step-by-step explanation:

(x,y)=(5,5)

So theta=arctan(5/5)=arctan(1)=45 degrees

Now r! r=sqrt(x^2+y^2)=sqrt(5^2+5^2)=sqrt(50)=sqrt(25)sqrt(2)=5sqrt(2)

So one polar point is (5sqrt(2) , 45 degrees)

Now if we do 180+45=225 degrees... this puts us in the 3rd quadrant... to get back to quadrant 1 we just take the opposite of our r

so another point is (-5sqrt(2) , 225 degrees)

answer: 25.4 units

step-by-step explanation: radius = 12.7 units

diameter = twice the radius

diameter = 12.7 x 2

= 25.4
