A triangle has angle measures of 75°, 41°, and (3x+19)°. Solve for x

1 answer

The sum of the angles in a triangle is always 180°.
So, we have the equation:

75° + 41° + (3x+19)° = 180°

Combining like terms, we have:

(3x + 135)° = 180°

Subtracting 135° from both sides:

3x = 45°

Dividing both sides by 3:

x = 15°

Therefore, x = 15°.
