To find the value of x, we need to use the fact that the sum of all angles in a triangle is always 180°.
So, we can set up an equation:
75 + 41 + (3x + 19) = 180
Combine like terms:
(3x + 135) = 180
Subtract 135 from both sides:
3x = 180 - 135
3x = 45
Divide both sides by 3:
x = 45 / 3
x = 15
Therefore, x = 15.
So, we can set up an equation:
75 + 41 + (3x + 19) = 180
Combine like terms:
(3x + 135) = 180
Subtract 135 from both sides:
3x = 180 - 135
3x = 45
Divide both sides by 3:
x = 45 / 3
x = 15
Therefore, x = 15.
