The hypotenuse of a right-angled triangle is 30cm. One side is 24cm. Find the length of the other side.

Answer 1

We can use the Pythagorean theorem to solve for the length of the other side of the triangle:

c^2 = a^2 + b^2

where c is the hypotenuse and a and b are the other two sides.

Substituting the given values, we get:

30^2 = 24^2 + b^2

Simplifying and solving for b, we get:

900 = 576 + b^2

b^2 = 324

b = sqrt(324) = 18

Therefore, the length of the other side of the triangle is 18cm.
