## Question 4
**Problem Statement:**
Find cos(B) given the triangle.
**Diagram Description:**
- The diagram shows a right triangle with the following sides:
- The side opposite the right angle (hypotenuse) is labeled as 195.
- The side adjacent to angle B is labeled as 99.
- The remaining side is labeled as 168.
- Angle B is denoted in the triangle, adjacent to the side labeled 99 and opposite the side labeled 168.
**Guidance for Solving the Problem:**
To find cos(B):
- Recall that the cosine of an angle in a right triangle is the ratio of the length of the adjacent side to the hypotenuse.
- Use the formula:
\[ \cos(B) = \frac{\text{Adjacent Side}}{\text{Hypotenuse}} \]
- Plug in the given values:
\[ \cos(B) = \frac{99}{195} \]
