Answer:
- 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
