Answer 2

Answer:

scalene triangle ; obtuse angled triangle

Step-by-step explanation:

m∠A + m∠B + m∠C = 180°

x + 35° + 3x + 80° + x - 10° = 180°

5x + 105° = 180°

5x = 75°

x = 15°

m∠A = 15° + 35° = 50°

m∠B = 3(15°) + 80° = 125°

m∠C = 5°

AB ≠ BC ≠ AC ⇒ Δ is scalene triangle

∠B is obtuse angle ⇒ Δ is obtuse angled triangle
