If ∠G is supplementary to ∠H and the measure of ∠G is 65° what is the measure of ∠H?
Elina [12.6K]

Solution:

<u>Given:</u>

  • ∠G = 65°

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

<u>It should be noted:</u>

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

Equation formed: ∠G + ∠H = 180

<u>Substitute the values into the equation.</u>

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

<u>Subtract 65 both sides.</u>

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