To find the value of x in the triangle with angle measures of 75, 41, and (3x + 19), we use the fact that the sum of the angles in a triangle is always 180 degrees.
So, we add up the three angle measures and set the sum equal to 180:
75 + 41 + (3x + 19) = 180
Simplify the equation:
116 + 3x + 19 = 180
3x + 135 = 180
Now, subtract 135 from both sides:
3x = 45
Divide by 3 on both sides to solve for x:
x = 15
Therefore, x is equal to 15.
