The above diagram shows the intersection of two roads, their widths being 16m and 9m. If RN = x , and MP = y, how would you express y in terms of x. Is it by using the method of congruent triangles here? If so, how would it be done?

The word is similar triangles. Try it and show us what you can do (and then maybe ask about what you can't do). – David K Dec 10 '18 at 03:26

This is not a question about "linear algebra". Tags are changed. – xbh Dec 10 '18 at 03:52
