Question

The sides of a triangle are produced in order. If external angles formed are and 3x⁰, 4x⁰ and 5x⁰ find the value of x.​

Answer 1

Answer:

x = 30 .

Step-by-step explanation: Sum of exterior angles in a triangle is 360 degree . therefore , we can say that 3x + 4x + 5x = 360 , Where 3x,4x,5x are the exterior angles . Now we need to solve the equation .

3x + 4x + 5x = 360 . 12x = 360 .

x = 360/12 = 30 degree .

Thus , The Value of x is 30 degree .
