Solution

The correct option is A 75
Two angles are called supplementary angles if their sum is 180 $^{\circ}$ .

So, 30 $^{\circ}$ + 2x = 180 $^{\circ}$

Hence, x = 75 $^{\circ}$ .

An angle of measure 30∘ and twice of another angle x are supplementary angles. Find the value of x (in degrees).75

The correct option is A 75Two angles are called supplementary angles if their sum is 180∘. So, 30∘ + 2x = 180∘ Hence, x = 75∘.
