To find the length of the missing side in a right triangle, we can use the Pythagorean theorem which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
In this case, we are given the lengths of sides b and c, and we need to find the length of the missing side, which we'll call 'a'. Let's follow the steps to find the length of side 'a':
1. Write down the Pythagorean theorem: a^2 + b^2 = c^2
Substitute the given values: a^2 + 2.1^2 = 2.9^2
2. Simplify the equation: a^2 + 4.41 = 8.41
3. Move the constant to the other side: a^2 = 8.41 - 4.41
4. Solve for a^2: a^2 = 4
5. Take the square root of both sides to find the value of 'a': a = √(4)
6. Simplify: a = 2
Therefore, the length of the missing side in this right triangle is 2 units.
