The diagonal of a square is 60 in, as shown in the diagram. What is the length of a side
to the nearest tenth of an inch?

The length of side is 42.4 inches.

Step-by-step explanation:

Given that:

Diagonal of square = 60 inches

As all sides of a square are equal, thus

Side of square = x

The diagonal will be the hypotenuse of a right angled triangle.

Using Pythagorean theorem;

Taking square root on both sides

Hence,

The length of side is 42.4 inches.

y = x + 95

y = 42 + 95

y=137 mm hg
