The measure of ∠x is 60°, and the measure of ∠y is 90°, the measure of ∠z is 30°
An angle is a mathematical term, which we can define, when two straight lines or rays meet at a common endpoint. The common point is called the vertex of an angle. The word angle comes from a Latin word named ‘angulus,’.
Interior angles:- The inner angle made by the intersection of two polygonal sides.
Exterior angles:- The outer angle made by the intersection of two polygonal sides.
Given that,
In right angle triangle, Δxyz
Angle ∠x is 60°
Angle ∠y is 90°
It is already known that sum of all the interior angles of any triangle is equal to 180°
So,
∠x + ∠y + ∠z = 180°
60° + 90° + ∠z = 180°
∠z = 30°
Therefore, the third angle is 30°

The area of original square is 16 centimetre square.
The area is the region bounded by the shape of an object.
Let consider 'a' as the side of the original square.
When it fold vertically then the top and bottom sides will be half of the original side.
The perimeter of folded square = 12 cm
i.e. (2* 0.5a)+ 2a =3a =12 cm
Then, a=4cm
The area of original square is given by a^2.
Then, a^2 = 4*4 =16
Hence, 16 centimeter is the area of the original square.
