The equation 18 to the second power+ b to the second power= 30 to the second power is found to be true. What do we know about the triangles? The triangle is a right triangle with a missing leg length of 24, the triangle is a right triangle on the legs are 30 and 24, the triangles are right triangle with a missing side of 34.99, the triangles is right triangle and the hypotenuse is 18

Based on the equation given (18^2 + b^2 = 30^2), we know that the triangle is a right triangle with the missing leg length of 24.

To analyze the given equation and determine the properties of the triangles, let's break down the equation step-by-step:

1. The equation is as follows: 18^2 + b^2 = 30^2

2. Simplifying the equation, we get: 324 + b^2 = 900

3. Subtracting 324 from both sides, we have: b^2 = 576

4. Taking the square root of both sides, we find: b = ±24

From the above steps, we see that the missing leg length, represented by 'b', can be either positive or negative 24. However, since we are working with a triangle, the length of a side cannot be negative. So, the triangle is a right triangle with a missing leg length of 24.

In summary, we know that the triangle is a right triangle with one leg measuring 24.

To determine what we know about the triangle, we need to analyze the given equation and the information provided.

The equation given is:
18^2 + b^2 = 30^2

To solve for b, we can start by simplifying the equation:
324 + b^2 = 900

Next, we can isolate b^2 by subtracting 324 from both sides of the equation:
b^2 = 900 - 324
b^2 = 576

Now, taking the square root of both sides, we find:
b = √576
b = 24

From the equation, we know that the missing leg, represented by b, has a length of 24 units.

Since we have the lengths of two legs of a right triangle, we can conclude that the triangle is indeed a right triangle with the leg lengths of 30 and 24. Therefore, the correct answer is that the triangle is a right triangle and the legs are 30 and 24.
