Martin has 12 times as many baseball cards as josie. josie has 29 more cards than kal. how many baseball cards does martin have?

I could work out this question but not exactly sure because I think that you need to find out how many kal has because kal is the problem here. once u figure that out. times the number by 12 and yeah. that would be your answer but idk how many kal has.

Ihonestly don’t no that

Its a right angled triangle not a right triangle
