Answer:
x=6.5
Explanation:
This question is on intersecting cords and segments that intersect outside the circle
Forming an equation for this relation;
6(x+6)= 5(5+10)
6x+36=5(15)
6x+36=75.............................collect like terms
6x=75-36
6x=39...........................divide both sides by 6
x=6.5
