Question

please help me with this

Answer 1

Answer:

2. 50° - Right Angled triangle

3. 60° - Acute angled triangle

Step-by-step explanation:

2. 90° + 40° + x = 180°

⇒ 130° + x = 180°

⇒ x = 180° - 130°

⇒ x = 50°

Since one angle is 90°, it is a right angled triangle.

3. 70° + 50° + x = 180°

⇒ 120° + x = 180°

⇒ x = 180° - 120°

⇒ x = 60°

Since all the angles are less than 90°, it is an acute angled triangle
