Answer:
PO = 36
Step-by-step explanation:
Since both the chords are equal in length so they must be equidistant from the centre.
And
PG = GO
-x+10 = -3(x+2)
-x+10 = -3x-6
-x+3x = -6-10
2x = -16
Dividing both sides by 2
x = -8
Now
PO = PG + GO
PO = -(-8)+10+(-3)((-8)+2)
PO = 8+10+(-3)(-6)
PO = 18+18
PO = 36
