In a triangle a angle is x degrees ,b angle is 2x degrees ,c angle is 105 degrees then find out the value of x ?
x + 2x + 105 = 180
3x + 105 = 180
Subtract 105 from each side of the equation.
3x + 105 - 105 = 180 - 105
3x = 75
Divide each side by 3
3x/3 = 75/3
Answer:
x = 25 degrees and
2x = 50 degrees
