1. **State the problem:** We have a right triangle where \(\sin(7x+2)^\circ = \cos(6x-3)^\circ\). We need to find the larger of the two acute angles.
2. **Recall the identity:** For any angle \(\theta\), \(\sin \theta = \cos(90^\circ - \theta)\).
3. **Apply the identity:** Since \(\sin(7x+2)^\circ = \cos(6x-3)^\circ\), it implies:
$$7x + 2 = 90 - (6x - 3)$$
4. **Solve the equation:**
$$7x + 2 = 90 - 6x + 3$$
$$7x + 2 = 93 - 6x$$
Add \(6x\) to both sides:
$$7x + 6x + 2 = 93$$
$$13x + 2 = 93$$
Subtract 2 from both sides:
$$13x = 91$$
Divide both sides by 13:
$$x = \frac{91}{13}$$
5. **Calculate the angles:**
\(7x + 2 = 7 \times \frac{91}{13} + 2 = \frac{637}{13} + 2 = \frac{637}{13} + \frac{26}{13} = \frac{663}{13} \approx 51\) degrees
\(6x - 3 = 6 \times \frac{91}{13} - 3 = \frac{546}{13} - 3 = \frac{546}{13} - \frac{39}{13} = \frac{507}{13} \approx 39\) degrees
6. **Identify the larger acute angle:** The two acute angles are approximately 51 degrees and 39 degrees. The larger is \(51^\circ\).
**Final answer:** The larger acute angle is \(51^\circ\).
