To find the length of the other leg in a right triangle, we can use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides.
In this case, we have a right triangle with legs of length 30 and 30, and we want to find the length of the other leg, which we can call x. So we have:
30^2 + 30^2 = x^2
Simplifying this equation gives:
1800 = x^2
Taking the square root of both sides, we get:
x = sqrt(1800) = 42.43 (rounded to two decimal places)
Therefore, the length of the other leg is approximately 42 (rounded to the nearest ten)
