Correct option is A
Given:
The angles of the triangle are in the ratio 2 : 3 : 4.
Formula Used:
1. The sum of the angles of a triangle:
Sum of angles = 180
2. Let the angles be 2x, 3x, and 4x . Use the equation:
2x + 3x + 4x = 180
Solution:
1. Solve for x :
2x + 3x + 4x = 180
9x = 180
x = 20
2. Find the three angles:
- First angle: 2x = 2 \times 20 = 40
- Second angle: 3x = 3 \times 20 = 60
- Third angle: 4x = 4 \times 20 = 80
Final Answer:
The three angles of the triangle are **40°, 60°, and 80°**.
