Hey There!
Let's setup.
5x+13 = 12x-8
Subtract 5 as it is lower.
12x - 5x =7x
We now have 7x-8=13
Add 8 on both sides.
13 + 8 = 21
We now have 7x = 21
Divide 7 from both sides.
21/7= 3
Therefore, x would equal to 3.
Hope this helped!
As two arcs are same means both chords would also be same.
5x + 13 = 12 x - 8
Adding 8 on both sides
5 x + 13 + 8 = 12 x - 8 + 8
5 x + 21 = 12 x
Subtracting 5 x from both sides
5x + 21 - 5x = 12 x - 5x
21 = 7 x
Dividing from 7
21/7 = 7x / 7
3 = x : Answer
Hope that will help.
