Answer:
x = 5
Explanation:
the radius (centre to edge) is the same right around the circle.
so that means that distance O to left edge of line that is 24 long = 13.
draw a line from O to top left end of 24 line. label that left end A. also, where the vertical line from O meets the 24 line, call that B. notice how OAB has just become a right-angled triangle?
we can see that AB = 12.
we have a right-angled triangle.
x is the length OB.
OB² = 13² - 12²
= 169 - 144
= 25
OB = √25 = 5.
OB = x = 5
