The value of x is the length GH, which is determined as 6.
Value of x
The value of x is the length GH and can be calculated from Pythagoras theorem.
|OG|² = |OS|² + |SG|²
|OG|² = 9² + 12²
|OG|² = 225
|OG| = √225
|OG| = 15
x + H = |OG|
where;
- H is radius of the circle = 9
x + 9 = 15
x = 15 - 9
x = 6
