Answer:

see explanation

Explanation:

The sum of the 3 angles in a triangle = 180° , then Δ EGF

∠ G = 180° - (90 + 30)° = 180° - 120° = 60°

------------------------------------------------------------

c and g are adjacent angles and sum to 180° , then

c + g = 180° , that is

c + 60° = 180° ( subtract 60° from both sides )

c = 120

That is ∠ C = 120°

Finishing the angles of the smaller triangle if E is 90 and F is 30 then G needs to be 180-90-30 = 60 degrees.

Angles G and C are supplementary angles which need to equal 180 degrees

Angle c = 180-g = 180-60 = 120

Angle c = 120 degrees.
