Answer: The value of w is 60 degrees...
It's simple!
It is a triangle as it has 3 angles. Now if we add all the three angles, it is always 180 degrees... And the square angle on the corner always represents 90 degrees. So we know two angle value, just find the other one," w " Let's place it in a formula:
1st angle + 2nd angle + 3rd angle = 180 degree angle
30 degree + 90 degree + w angle = 180 degree angle
120 degree + w angle = 180 degree angle
w angle = 180 degree - 120 degree
w = 60 degrees!
