Math Problem Statement
Solution
From the image, we can see a right triangle with the following given information:
- One of the angles is .
- The side adjacent to this angle has a length of 15 units.
To find the missing side lengths, we can use trigonometric ratios:
-
Cosine function relates the adjacent side and the hypotenuse: Rearranging for the hypotenuse:
-
Sine function relates the opposite side and the hypotenuse: Once we know the hypotenuse, we can use this to find the opposite side:
Let me compute these values for you.
- Hypotenuse
Now, using the hypotenuse to find the opposite side:
- Opposite side
So, the hypotenuse is approximately 31.94 units, and the opposite side is approximately 28.19 units.
Would you like more details or have any questions about these calculations?
Here are some related questions to consider:
- How does the tangent function relate the opposite and adjacent sides?
- Can you calculate the angle opposite the missing side using another method?
- How would these results change if the triangle were not a right triangle?
- Could the Pythagorean theorem also be used to verify the missing side lengths?
- How would you find the area of this triangle?
Tip: When using trigonometric functions, always ensure your calculator is set to the correct mode (degrees or radians).
