Answer:
see explanation
Step-by-step explanation:
The 2 angles are adjacent and supplementary, thus
2x + x + 84 = 180 , that is
3x + 84 = 180 ← required equation
Subtract 84 from both sides
3x = 96 ( divide both sides by 3 )
x = 32
Thus
∠ 1 = 2x = 2(32) = 64°
∠ 2 = x + 84 = 32 + 84 = 116°
A compass is used to copy an angle.
The answer is C.
