Answer:
According to the given attachment
L is a straight line and we know Sum of all angles formed on a straight line is 180° .
So,
➠ a + 90° + b = 180°
➠ a + b = 180° - 90°
➠ a + b = 90°
If angle a = angle b so we can easily find the value of a & b .
So, according to me " the given figure has not enough information to find out the value of a & b .
