Question

Find the side of a square whose diagonal is of the given measure.
Given = 15.2 cm

Answer 1

15cm

Explanation:

Each corner of the square would be a 90° angle so half of that would be 45°.

`\sin(45) * 15 √(2) = 15cm`

Answer 2

15cm

Explanation:

First, a square's diagonal is basically the hypotenuse of a 45-45-90 triangle. a 45-45-90 triangle has a really special relationship, where the side length is x, and the diagonal is x
`√(2)`. So, the side length is 15.
