I know the answer to this but I need help explaining
![**Problem 4:**
Find \( x \). The figure is not drawn to scale. Is the triangle equilateral, isosceles, or scalene?
Diagram:
The diagram depicts a triangle \( \triangle PQR \) inscribed in a circle, with the following angle measures:
- Angle \( P \) is labeled as \( (6x + 5)^\circ \).
- Angle \( Q \) is labeled as \( (9x + 15)^\circ \).
- Angle \( R \) is labeled as \( (5x)^\circ \).
Given:
\[ x = 17 \]
Type of triangle:
\[ \text{scalene} \]
**Problem 5:**
In circle \( O \), \( BC = 13 \) and \( DC = 24 \). The diagram is not drawn to scale. What is the length of the diameter \( BA \)? Round the answer to the nearest tenth.
(Note: For the image displayed, precise measurements and calculations specific to the context are needed for complete solutions.)](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F4785896d-5cab-40ee-a849-415a4e58e278%2Fcf1529b2-827d-475b-bb40-930304b7aff5%2Fm5ww19i_processed.jpeg&w=3840&q=75)
