Question

f

Answer 1

I'm assuming the 6x+4 line is parallel to the line 4x+56?

Answer 2

find for x
6x+4=4x+56

Answer 3

If it is then it's about ratios. So the ratios of the smaller triangle to the whole, big triangle. Since the sides you're given are the same, it's clear the ratio of large triangle to small is 2:1, which means that applies to the x equations as well!
You should be able to do quite a simple equation from that, of 2(6x+4)=4x+56

Answer 4

I don't think they equal, the bottom line is double the top!

Answer 5

i think you're finding the angle
i just done this last week

Answer 6

then substitute in for X to find the angle

Answer 7

but then i might be totally wrong...

Answer 8

Which angle? I was just finding x!

Answer 9

There's no need to assume. There is a throrem about this. In a triangle, a line segment joining the midpoints of two sides is parallel to the third side and half as long as the third side.
