The sum of angles in the triangle is 180 degrees. Therefore, the value of x in the triangle is 35
The sum of angles of a triangle is 180 degrees. This simply implies the sum of the three angles in a triangle is equals to 180 degrees.
Therefore,
x + 10 + 3x - 5 + x = 180
combine like terms
x + x + 3x + 10 - 5 = 180
5x + 5 = 180
subtract 5 from both sides of the equation
5x + 5 - 5 = 180 - 5
5x = 175
divide both sides by 5
5x / 5 = 175 / 5
x = 35
