Analyze the diagram below and complete the instructions that follow. find m

Check the picture below.

notice, the missing interior angle is a linear angle with ∡FEG, therefore, both of them add up to 180°, so the missing interior one is the difference of
[ 180° - (x + 4) ].

also recall that the sum of all interior angles in a triangle add up to 180°.

so, let's add them up then,
