Question 535096: The measures of the three angles of a triangle are represented by x, 3x, and x+30. What is the value of x? Answer by lmeeks54(111) (Show Source):
You can put this solution on YOUR website! This problem requires knowing that the sum of the interior angles in any triangle = 180 deg. We are given the 3 angles for the triangle in terms of x:
...
x
3x
x + 30
...
We know they must sum to 180:
...
x + 3x + (x + 30) = 180
...
Combine like terms and simplify:
5x + 30 = 180
...
Subtract 30 from both sides:
5x = 150
...
x = 30 deg
...
