Can someone help me with this question

Answer:
[tex]x = 87[/tex]
2 ways of proof either
4 sides equal then equal Angles
or
cross diagonals if midpoints form equal Angles then Angles are equal
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
