Question

Use this diagram and information given to find m

Answer 1

The drawing seems to suggest that angles BFA, AFE and EFD span a straight angle, just like angles BFC and CFD

This means that you have

$BFA+AFE+EFD=180$

But we know that both BFA and EFD measure 70 degrees, so the equation becomes

$[tex]70+AFE+70=180 \iff AFE + 140 = 180$

So, if you subtract 140 from both sides, you have

$AFE = 180-140 = 40$
