Question

If three angles of triangle are 3x, 4x and 5X, the value of X is ?​

Answer 1

Step-by-step explanation:

3x+4x+5x=180°{ASP OF TRIANGLE }

12x=180°

×=180°/12

×=15°

Answer 2

• The sum of the 3 angles in a triangle is 180∘

• hence , the sum of the 3 angles given must equal 180

We can form an equation.

$2x + 3x + 4x = 180$

$9x = 180$

$x = \frac{180}{9}$

$x = 20$
