Point A is on the 4th circle from the center, each circle has a radius of 1, so the 4th circle has a radius of 4. The point is also on the angle labeled 5PI/6.
The polar coordinate would be (4, 5PI/6)
Point C, you are given (-3,pi/3)
Because the radius is positive find the 3rd circle, which would be r = 3, Then find where PI/3 is on the circle and find the value opposite that which is 4pi/3

Hello from MrBillDoesMath!
Answer: 9/25
Discussion:
My first observation is that both 36 and 100 are even numbers, so let's divide each by 2.
36/100 = 18/50
Again, 18 and 50 are even numbers so let's divided each by 2
= 18/50 = 9/25
While I didn't write it out, my statement "divide them by 2" is really this:
36/100 = ( 36/2) / (100/2) = (18) /50 = ( 18/2) / (50/2) = 9/25
Confusing, isn't it!
A shorter, but equivalent, approach is to divide the numerator and denominator by 4.

Let's assume the unknown number is x and as another one is 5 times the number then second number is 5x
》x × 5x = 245
》5x square =245
》x square =245÷5
》x square =49
》x=7
So 5x = 5×7=35
