Calculate the value of X in square DCBA

Answer:
45 degree , bc the ends are all 90 degree so divide 90 by two since the line crosses right in between
Answer:
45°
That looks like an Isosceles triangle so two sides are equal
The angle near O would be 90° cause that looks like an right angle
180-90=90
To find each angle divide by 2
90÷2=45
