I'm a little confused by your question.
You said 60-8 = 52 which is true.
Then, you asked 4x = 52 in an integer form
x = 52/4
x = 13. (Is that what you're asking?)
I'm not sure if this helps, but please comment if you need any help! Hope this helps though! :D

The line bisects the cord which we have to find
- Length of chord=12cm
- Half of the cord=12/2=6cm
- Radius=10cm
Its a right angle triangle
- using Pythagorean theorem
Distance of the chord from centre is 8cm.
A=bh/2
h=2A/b
h=2*175/16
h=21.875
h^2=s^2-(b/2)^2
h^2=s^2-b^2/4
h^2=(4s^2-b^2)/4
4h^2=4s^2-b^2
4s^2=4h^2+b^2
s^2=(4h^2+b^2)/4
s=√((4h^2+b^2)/4), since h=21.875 and b=16
s=√542.515625
s≈23.3 ft
Recall that "complementary angles" add up to 90 degrees, and that "supplementary angles" to 180 degrees.
If the given angle is 36 degrees (for example), the compl. angle is (90-36) degrees.
Try again to choose the correct solution.
