Sagot :
Answer:
- m∠H = 76°
Step-by-step explanation:
Given triangle HIJ with:
- ∠I ≅ ∠J
- m∠I = 3x + 34
- m∠J = 2x + 40
Find the value of x first, solving the following equation:
- 3x + 34° = 2x + 40°
- 3x - 2x = 40° - 34°
- x = 6°
Find the angle measure of I and J:
- 3*6° + 34° = 18° + 34° = 52°
Find the measure of angle H:
- m∠H = 180° - 2*52° = 180° - 104° = 76°
