In a triangle, the sum of all three angles is always equal to 180 degrees.
Therefore, we can set up an equation to find x:
(2x + 4) + (2x - 9) + x = 180
Simplifying the equation:
5x -5 = 180
Adding 5 to both sides:
5x = 185
Dividing both sides by 5:
x = 37
So the value of x is 37.
There is a triangle with 3 sides. Angle A is (2x+4). Angle B is (2x-9). Angle C is x. Find x.
