Question

In the figure below, OB is the radius of the arc BP.AB = 3 OA What number does point P represent?​

Answer 1

Answer:

OB=OP (since both are radius of same circle )

OB=√(3^2+1^2)=√10

hence OP=√10

There for the point P is (√10,0)

Answer 2

Given:

OB is the radius of arc BP.

AB = 3OA

To Find:

number point P represents.

Solution:

As we can see in the figure, both OA and OP are the radius of the same circle

So,

        OA = OP [Radius of the same circle]

        OB = $\sqrt{3^{2} + 1^{2} }$

               = $\sqrt{10}$

    So, OP = $\sqrt{10}$

Now, point P is ($\sqrt{10}$,0).

Therefore, point P represents (√10,0).
