The correct answer is
72°
Since the sum of angles in a triangle is \(180°\), and the ratio is \(3:3:4\) with total parts \(= 3+3+4 = 10\).
Value of one part \(= \frac{180°}{10} = 18°\).
The largest angle corresponds to 4 parts: \(4 \times 18° = 72°\).
Hence, the measure of the largest angle is 72°.
