I found G and F but I’m stuck on H please help me!!

Determine the measure of each missing angle Angle f 69 Angle g 69 Angle h I found G and F but I m stuck on

Answer :

Answer:

  • Angle f = 69°
  • Angle g = 69°
  • Angle h = 125°

Step-by-step explanation:

Angles f and g are congruent as opposite sides are congruent. Therefore:

  • g = f = (180° - 42°)/2 = 138°/2 = 69°

Angles h, 76°, g and the right angle all together form 360°:

  • h + 76 + g + 90 = 360
  • h + 166 + 69 = 360
  • h + 235 = 360
  • h = 360 - 235
  • h = 125
