I see that you've uploaded a math assignment related to trigonometry. The tasks listed include topics such as arc length, sector area, trigonometric equations, and coordinate geometry. Let's focus on the specific problems mentioned:

### Problem 1:
*A golfer hits a ball B a distance of 170 m on a hole that measures 195 m from tee to hole. If his shot is directed 10° away from the direct line to the hole, find how far his ball is from the hole.*

This is a problem involving the **Law of Cosines**, since the golfer's shot forms a triangle with the tee, the hole, and the ball.

We have:
- Side \( c = 195 \) m (distance from the tee to the hole),
- Side \( a = 170 \) m (distance from the tee to where the ball lands),
- Angle \( C = 10^\circ \) between the ball’s direction and the direct line to the hole.

We need to find the distance \( b \) from the ball to the hole.

The Law of Cosines is:
\[
b^2 = a^2 + c^2 - 2ac \cdot \cos(C)
\]
Let's calculate the value of \( b \).

### Problem 2:
*Find two possible values of \( c \) in triangle ABC given that \( a = 16 \, \text{cm}, b = 10 \, \text{cm}, \) and \( B = 30^\circ \).*

This problem also requires the **Law of Cosines** or **Law of Sines**, depending on the approach.

For now, I'll calculate the answer to Problem 1 using the Law of Cosines.

Let me calculate that.The distance from the golfer's ball to the hole is approximately **40.40 meters**.

Would you like to proceed with solving Problem 2, or do you have any questions about the first one?

Here are 5 related questions that expand on this:

1. How is the Law of Cosines derived from the Pythagorean theorem?
2. What are some real-life applications of the Law of Cosines?
3. How can the Law of Sines be applied to non-right triangles?
4. What is the importance of converting degrees to radians in trigonometry problems?
5. How does trigonometry help in navigation and determining distances?

**Tip:** When using trigonometric laws, always ensure that your calculator is set to the correct mode (degrees or radians) based on the problem.

A golfer hits a ball B a distance of 170 m on a hole that measures 195 m from tee to hole. If his shot is directed 10° away from the direct line to the hole, find how far his ball is from the hole. Find two possible values of c in triangle ABC given that a = 16 cm, b = 10 cm, and B = 30°.

Solve trigonometric problems involving the distance of a golf ball from the hole using the Law of Cosines. This problem includes finding the distance based on given sides and angles and is suitable for students in Grades 10-12.
