Question

Assertion : If the points A(4,3) and B(x,5) lies on a circle with the centre O (2,3) then the value of x is 2. Reason: The mid-point of the line segment joining the points P(x₁ , y₁) and Q (x₂ , y₂) is (x₁ + x₂)/2, (y₁ + y₂)/2

Answer 1

hope it helps. please Mark brailliast

Answer 2

Answer:

The assertion is true but the reason is false

Explanation:

Points A(4,3) and B(x,5) lies on a circle with the centre O (2,3)

OA = OB

$\sqrt{(4-2)^2+(3-3)^2} =\sqrt{(x-2)^2+(5-3)^2 } \\2=\sqrt{(x-2)^2+4} \\(x-2)^2+4=4\\(x-2)^2=0\\x=2$

Subtraction:

Subtraction serves as a representation for the act of removing items from a collection. The negative symbol stands for subtraction. For example, if four of the nine oranges that are stacked together (as in the above illustration) are then transported to a basket, the stack will now contain five oranges rather than nine. Therefore, the difference between 9 and 4 is 5, which equals 9 minus 4. In addition to applying it to natural numbers, subtraction can also be used with other kinds of numbers. The letter "-" represents subtraction. Minuend, subtrahend, and difference are the three numerical components that make up the subtraction operation.
