The sides of a triangle measure 5 cm, 8cm, and x cm

x = √89

Step-by-step explanation:

To find the 3rd side of any triangle using the other 2 known sides is simple.

First you want to identify the hypotenuse. It will be the longest side, opposite of the largest angle. The hypotenuse will represent c in the Pythagorean Theorem equation: a² + b² = c²

a and b will represent the other two sides.

When solving, I am assuming that the given sides are not the hypotenuse because it is unclear.

5² + 8² = √89

C 73

Bcs straight line is 180ns9 the angle should be 34.

So you equate 34=-39+x and u get x as 73
