- The image displays a right-angled triangle with one vertical side labeled 75 millimeters.
- An angle within the triangle is marked as 15 degrees.
- A side opposite the 15-degree angle is labeled \(x_2\).
- To the right of the triangle, a trigonometric equation is presented: \(\text{cos}(15^\text{o}) = \frac{x_2}{0.75}\).
- Following the equation, the conclusion \(\text{hence } x_2 = 72 \text{ millimeters}\) is written.
