Math Problem Statement

Find the remaining side log a 30°-60°-90° triangle if the median side is 6.

Solution

In a 30°-60°-90° triangle, the sides have specific ratios. The relationship between the sides is as follows:

  • The side opposite the 30° angle is the shortest side (let's call it xx).
  • The side opposite the 60° angle is x3x\sqrt{3}.
  • The hypotenuse (opposite the 90° angle) is 2x2x.

You mentioned that the "median side" is 6. It's important to note that in a 30°-60°-90° triangle, the median to the hypotenuse is half the length of the hypotenuse.

So, let's denote the hypotenuse by 2x2x. The median to the hypotenuse is half of the hypotenuse, which gives:

2x2=x\frac{2x}{2} = x

We are given that the median is 6, so:

x=6x = 6

Now, we can find the remaining sides:

  1. The shortest side (opposite the 30° angle) is x=6x = 6.
  2. The side opposite the 60° angle is x3=63x\sqrt{3} = 6\sqrt{3}.
  3. The hypotenuse is 2x=122x = 12.

Thus, the remaining side (the side opposite the 60° angle) is 636\sqrt{3}.

To summarize:

  • The shortest side: 6
  • The side opposite the 60° angle: 636\sqrt{3}
  • The hypotenuse: 12

Here are some related questions:

  1. How do you calculate the area of a 30°-60°-90° triangle?
  2. What is the relationship between the median and the sides in other types of triangles?
  3. How can you prove the side ratios for a 30°-60°-90° triangle using trigonometry?
  4. What happens if the median side is not given in a 30°-60°-90° triangle?
  5. How would you solve for missing sides in a 45°-45°-90° triangle?

Tip: Always remember that in a 30°-60°-90° triangle, the median to the hypotenuse is always half of the hypotenuse.
