Let the angle be x.
Then, its supplement = (180 - x)
Now,
x = 2( 180 - x ) - 30
=> x = 360 - 2x - 30
=> x + 2x = 360 - 30
=> 3x = 330
=> x = 330/3
=> x = 110
Hence, the angle is 110° .

The value of angle is 110°
GIVEN
An angle is 30 degree less than 2 times its supplement. find the angle.
TO FIND
Find the angle.
SOLUTION
We can simply solve the above problem as follows;
Angles are known as supplementary angles if their sum is equal to 180°
Let the angle be x
Supplimentary angle = y
Therefore,
x + y = 180° (Equation 1)
It is given that, angle is 30 degree less than 2 times its supplement.
Therefore,
x = 2y-30
So,
y = x + 30/2 (Equation 2)
Putting the value of y from equation 2 in equation 1.
Hence, The value of angle is 110°
