What is the value of $$c^2 - b^2$$ if c = 5 and b = 4?

Using the formula: $$c^2 - b^2 = 5^2 - 4^2 = 25 - 16 = 9$$ .

What is the value of $$c^2 - a^2$$ if c = 13 and a = 5?

Using the formula: $$c^2 - a^2 = 13^2 - 5^2 = 169 - 25 = 144$$ .

If $$c^2 - a^2 = 21$$ , what could be the values of c and a?

One possible solution is c = 25 and a = 20, since $$25^2 - 20^2 = 625 - 400 = 225$$ .

What does it mean if $$c^2 - b^2 = 0$$ ?

If $$c^2 - b^2 = 0$$ , it means that the two legs of the triangle are equal, making it an isosceles right triangle.

How do you calculate the hypotenuse if both legs are known?

To calculate the hypotenuse (c) when both legs (a and b) are known, use the formula: $$c = \text{sqrt}(a^2 + b^2)$$ .

What is the significance of the Pythagorean theorem in real life?

The Pythagorean theorem is used in various fields such as architecture, construction, navigation, and physics to determine distances and angles.

If $$c = 15$$ and $$b = 9$$ , what is $$a$$ ?

Using the formula $$a^2 = c^2 - b^2$$ : Here, $$a^2 = 15^2 - 9^2 = 225 - 81 = 144$$ . Therefore, $$a = 12$$ .

What is the formula to find the length of a leg when the hypotenuse and the other leg are known?

The formula is: $$a^2 = c^2 - b^2$$ or $$b^2 = c^2 - a^2$$ .

If $$c = 17$$ and $$a = 8$$ , what is $$b$$ ?

Using the formula $$b^2 = c^2 - a^2$$ : Here, $$b^2 = 17^2 - 8^2 = 289 - 64 = 225$$ . Therefore, $$b = 15$$ .

What is the importance of understanding the Pythagorean theorem?

Understanding the Pythagorean theorem is crucial for solving problems related to right triangles, which are foundational in geometry and trigonometry.
