To find the measurement of the smallest angle of the triangle, we need to first find the value of x.
Since the sum of the three angles in a triangle is always 180 degrees, we can set up an equation:
96° + 2x + x + 12° = 180°
Combine like terms:
109° + 3x = 180°
Subtract 109° from both sides:
3x = 71°
Divide by 3:
x = 23.67°
Now that we have found the value of x, we can substitute it into one of the angle measures to find the smallest angle.
The angles of the triangle are:
96°, 2(23.67°), 23.67° + 12°
96°, 47.34°, 35.67°
The smallest angle is 35.67°.
