Solution:

Given:

  • ∠G = 65°

Supplementary angles are a pair of angles that sum up to 180°.

It should be noted:

  • If ∠G and ∠H are a pair of supplementary angles, they both sum up to 180°.

Equation formed: ∠G + ∠H = 180

Substitute the values into the equation.

  • ∠G + ∠H = 180
  • => 65 + ∠H = 180

Subtract 65 both sides.

  • => 65 - 65 + ∠H = 180 - 65
  • => ∠H = 180 - 65 = 115°
