Question

Marks worth is A 1 B 2 C 2 Please explain next to it though how you got that answer and what to write to get that mark. Clearly explain as I have no clue, don't leave anything out though!
Information needed to solve

There is an isosceles triangle with corners A, B and C. Anyway corner A to B which is a side 4x-3 over 15. Corner A to C x+3 over 5. Corner B to C 5x+6 over 33. These are all on the outside of the triangle. Above is the explanation of the diagram. All lengths are in centimetres.

Questions
A. Write down an equation for x.
B. Solve the equation.
C. Work out the length of BC.

Answer 1

well, you didn't say which side is the base, and which are the two equal sides. I will assume A is the vertex between the two equal sides. In that case, AB = AC, so

(A): (4x-3)/15 = (x+3)/5
I assume you can now work out the rest.

If I got the two equal sides wrong, then fix it and devise a similar equation.

Answer 2

Thanks! By the way what is this sort of question called?
