Answer:
The other leg is 16.6 cm (approximately)
Step-by-step explanation:
We have a right triangle, with the hypotenuse = 18, one side = 7, and the other side = x.
Since this is a right triangle, we will use the Pythagorean Theorem to find the value for x.
So, let a = 7 for one side, and let c = 18 for the hypotenuse. And, let c = x for the other side.
The Pythagorean Theorem is:
c^2 = a^2 + b^2.
So, 18^2 = 7^2 + x^2
324 = 49 +x^2
And, x^2 = 324 - 49 = 275
So, x = sqrt(275) = 16.58 cm (approximately).
Conclusion: The other leg is 16.6 cm (approximately).
