Let an angle of a triangle is . If the variance of the angles of the triangle is , then the other two angles are
- A
- B
- C
- D
Answer & Solution
Correct Answer
(C)
Step-by-step Solution
Detailed explanation
Let three angles of triangle be x, y & z. As sum of three angles of triangle=180°. ⇒x+y+z=180° ⇒60°+y+z=180° (Given one angle is 60∘) ⇒y+z=120° …1 Now, it is given that variance of the angles of…
