triangle

a = 18
b = 80
c = ?

To find the value of "c" in the triangle, we can use the Pythagorean theorem.

The Pythagorean theorem 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, "a" and "b" are the lengths of the two sides, and "c" is the length of the hypotenuse.

Applying the Pythagorean theorem:

c^2 = a^2 + b^2
c^2 = 18^2 + 80^2
c^2 = 324 + 6400
c^2 = 6724

Taking the square root of both sides to find "c":

c = √6724
c ≈ 81.98

Therefore, "c" is approximately 81.98.
