The hypotenuse of a right triangle is 15 cm. One of the triangles legs is two times the length of the other leg

Step-by-step explanation:

to solve you will use the formula c2=a2+b2 where c2 is always the hypotenuse and a2 and b2 are the rest of the sides. So c2 will be (15)2 and a2 will be (2x)2 while b2 will be represented by x2.Calculate (15)2=(2x)2+x2 You will get 225=4x2+x24x2+x2 will give you 5x2Then you will divide 225 by 5x2 and find the square root of it.√45 is an irritational number since it has no perfect square so you will use the long division method.Your answer will be 6.708
