You have to use the Pythagorean Theorem. Follow what I do, and if you have any questions be sure to tell me. a^2+b^2=c^2 This is the formula. But don't get worried by the variables, you can always switch a and b for l and m. Also c can be switched for n. So not to get this confusing, I will substitute the letterings for you, l^2+m^2=n^2 Lets now substitute the variables with the numbers. 12^2+5^2=c^2 169=c^2 Remember that n equals to the square root of 169. n= √169 n=13

there are 12 students working in a library if three Fourth of them are girls how many girls are working in the piano

Len [333]

I don’t really get your question, because you said that ¾ of them are girls, Then how many girls are working in the piano? You did not stated the question well. However, I will try to answer this base on my understanding. There are a total of 12 students that works in the library. IF ¾ of them are girls: => 12 / 4 = 3 *3 = 9 => 9 of them are girls and 3 of them are boys. Thus, how many girls are working in the piano. The probability is 9, there might be 9 girls working in the piano, or less than 9. Since you did not mention how many girls worked in different part of the library.
