1. **State the problem:** We have a triangle with one angle measuring 30° and the other two angles in the ratio 13:17. We need to find the measures of these two angles.
2. **Recall the triangle angle sum rule:** The sum of the angles in any triangle is always 180°. So,
$$\text{Angle}_1 + \text{Angle}_2 + \text{Angle}_3 = 180^\circ$$
3. **Assign variables:** Let the two unknown angles be $13x$ and $17x$ based on the given ratio.
4. **Set up the equation:** Using the sum of angles,
$$30 + 13x + 17x = 180$$
5. **Simplify the equation:**
$$30 + 30x = 180$$
6. **Isolate $x$:**
$$30x = 180 - 30$$
$$30x = 150$$
$$x = \frac{150}{30}$$
$$x = 5$$
7. **Find the angles:**
$$13x = 13 \times 5 = 65^\circ$$
$$17x = 17 \times 5 = 85^\circ$$
8. **Check the sum:**
$$30 + 65 + 85 = 180^\circ$$ which confirms the solution is correct.
**Final answer:** The two angles measure $65^\circ$ and $85^\circ$.
