Question

If the points A (4, 3) and B(x, 5) are on the circle with the centre
0 (2, 3), find the value of x.​

Answer 1

Answer:

x=2

Step-by-step explanation:

Distance between centre and point on a circle is equal

$\sqrt{ (4-2)^{2} + (3-3)^2} = \sqrt{ (x-2)^{2} + (5-3)^2}$

$\sqrt{4+0} = \sqrt{(x-2)^2 + 4}\\\\4 = (x-2)^2 + 4\\\\(x-2)^2 = 0\\\\x = -2/2$
