Question

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 H please help me!!

Answer 1

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

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
