Angle 30∘ and twice of another angle x are supplementary angles. Find the value of x (in degrees)___.
Two angles are called supplementary angles if their sum is 180∘.
So, 30 ∘ + 2x = 180 ∘
x = 75∘
There exist two supplementary angles such that one of them is 30∘ and the other one is two times some arbitrary angle x. Find the value of x (in degrees).
If ∠A = 2x and ∠B = 4x such that ∠A and ∠B are supplementary, then the value of x is:
