s = 13
your answer is 13
Answer: 5/11
Tip:
You can solve for these repeating fractions by putting the repeating digits over 9's!
For example, 0.33 repeating:
33/99 = 1/3
And in the case of your problem:
0.454545...
45/99 = 5/11 (simplify!)
Answer: x=8
How: 41 the triangles are mirrored, so they have the same angles. You are trying to find the bottom angle of the top triangle, which is the same as the top angle of the bottom triangle since they are mirrored. So, (5x+1) is equal to 41. 41-1 =40. 40/5=8. Boom.
