Question

Find UV.

Answer 1

Assuming U is bisecting the angle, that'd make the sides opposite equal to each other
such that 5x+9 = 7x+1

Answer 2

@bibby so then x = 4?

Answer 3

Unless anyone else watching the question right now has any objections, I believe it is.

Answer 4

@bibby im still confused on what UV is though?

Answer 5

UV==QU
They are both 5(4) + 9 = 29

Answer 6

@bibby so UV = 29?

Answer 7

Yeah. Do you see how both triangles have the same angle measurements?

Answer 8

@bibby yeah I get it more now, thanks :)
