Question

What's is the is the equation

Answer 1

the third angle is 19.5°

Step-by-step explanation:

∠G = 33.5°

∠ H = 127°

∠ F = ?

∠G + ∠H + ∠F = 180° (sum of angles in a triangle)

33.5 + 127 + ∠F = 180°

160.5 + ∠F = 180

subtract 160.5 from both sides:

160.5 - 160.5 + ∠F = 180 - 160.5

∠F = 19.5°

Hence, the third angle is 19.5°
