Question

Which of the following statements must be true about this diagram? Check all that apply.
​

Answer 1

b,c,f

Explanation:

in a triangle, the sum of all angles is 180°

on a straight line, the sum of all angles is also 180°

so we get:

`x + y + z = 180 \\ w + z = 180`

and then this (there is a theorem about this, but the proof is simple enough):

`w = x + y`

since x, y, w are positive values:

`w > y \\ w > x`
