Find the length of the unknown side. round your answer to the nearest tenth. image of a right triangle with a leg of 4, hypotenuse of 18, and second leg unknown. 16.5 17.5 18.5 22.0

Length of another side is 17.5 unit (Approx.)

Given that;

Length of one side = 4 unit

Length of hypotenuse = 18 unit

Find:

Length of another side

Computation:

Using Pythagorean theorem;

H² = P² + B²

Length of another side = √18² - 4²

Length of another side = √324 - 16

Length of another side = √308

Length of another side = 17.5 unit (Approx.)

Right triangles...u can use the pythagorean theorem for this
a^2 + b^2 = c^2a and b are the legs and c is the hypotenuse
4^2 + b^2 = 18^2
16 + b^2 = 324
b^2 = 324 - 16
b^2 = 308...take the sqrt of both sides, eliminating the ^2
b = sqrt 308
b = 17.54 rounds to 17.5 <== ur other leg
