Question

How do I break down these triangles? It's tough for me to visualize it properly, so I end up always plugging in the wrong numbers because I break them down incorrectly.

Answer 1

it might help to break down the triangles and re-arrange them to the same position so the proportion is easier to make

Answer 2

ok

Answer 3

scratch that, draw QDP and PDR

Answer 4

then it's clearly x/10 = 4.9/x, you can then cross multiply and solve for x

Answer 5

ok

Answer 6

yeah you have the right idea

Answer 7

is that all there is to it?
it would be x^2=49?
there's no third triangle?

Answer 8

yeah
we can solve by creating 2 triangles, so in this case there's no point making another

Answer 9

would this be correct for #12

Answer 10

x/10=10/25

Answer 11

good
