What is the supplementary angle of 150-a (degree)?

Step 1. The supplementary angle is when two angles add up to 180 degrees.

Step 2. For this example, 150-a+b=180 where b is the supplementary angle.

Step 3. Then subtracting 150-a from both sides of the equation yields

150-a%2Bb-%28150-a%29=180-%28150-a%29

b=30%2Ba

Step 4. The supplementary angle is b=30+a

I hope the above steps were helpful.
