The angles of a triangle are 3x^, (2x+60)^ and (5x-40)^. Then the value of x is: Option 1: 14 Option 2: 18 Option 3: 16 Option 4: 20

Answer: 16. Solution: Sum of angles of a triangle is 180^. So 3x + (2x+60) + (5x-40) = 180. Simplifying: 10x + 20 = 180, so 10x = 160, giving x = 16, which matches option 3.

The angles of a triangle are $3x^\circ$ , $(2x+60)^\circ$ and $(5x-40)^\circ$ . Then the value of x is:

✅ Correct Option: 3

Sum of angles of a triangle is $180^\circ$ . So $3x + (2x+60) + (5x-40) = 180$ . Simplifying: $10x + 20 = 180$ , so $10x = 160$ , giving $x = 16$ , which matches option 3.
