2 legs of a triangle are 15 and 7. What is the third legs value
To find the value of the third leg of a triangle, you 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, the two legs of the triangle are given as 15 and 7. So, let's call the third leg x.
By applying the Pythagorean theorem, we can write the following equation:
x^2 = 15^2 + 7^2
x^2 = 225 + 49
x^2 = 274
Taking the square root of both sides, we find:
x = √274
Hence, the approximate value of the third leg is √274, which is approximately 16.55.
