Answer:

87 degree

Step-by-step explanation:

The shape is a square, which means 4 sides are equal and the 4 Angeles are equal.

Or make a diagonal line across the square, find the length of the diagonal using pythagoras theorem

I.e (hypotenuse)²= length ²+breadth 2

let y =the length of the diagonal

y²= 3.2²+3.2²

y=4.52
