Question

What does x equal. 8, 9, or 10?​

Answer 1

x = 8

Explanation:

We can see that this is using power of a point or PoP! So we immediately know that 5x = 4*10.

So solving for x (by dividing by 5 on both sides) we get:

x = 8

Answer 2

Answer : The value of 'x' is, 8

Step-by-step explanation :

According to the theorem, if two chords intersect inside a circle then the product of the lengths of the one chord equals to the length of another chord.

That means in the given figure,

AO × OB = CO × OD

Given:

Length AO = 10

Length OB = 4

Length CO = x

Length OD = 5

Now put all the given values in the above expression, we get:

AO × OB = CO × OD

10 × 4 = x × 5

40 = x × 5

x = 8

Therefore, the value of 'x' is, 8
