In a right-angled triangle, the hypotenuse is 39cm and the ratio of the other two sides is 12:5. Find the sides
Hi Diophantus,
One of the right-triangle 'patterns' that you will likely see on the GMAT is the 5/12/13. It's important to remember that MULTIPLES of this ratio are also valid right triangles. Thus, you could have sides of...
5, 12 and 13
10, 24 and 26
15, 36 and 39
Etc.
Here, we know that the hypotenuse is 39 and the ratio of the two 'legs' is 5:12. Thus, those two legs must be...
15 and 36
