Question

pls help me I need the help I would appreciate it!!!

Answer 1

SOLUTION :-

Since, the pair of angles are supplementary

a + b = 180°

50° + b = 180°

b = 180° - 50°

→ b = 130°

Answer 2

Answer:

130°

Step-by-step explanation:

supplementary angles are two angles that add up to 180°

(they form a straight line)

So, because we know that ∠b and 50° are supplementary, they must add up to 180:

b + 50 = 180

   - 50     -50             (subtract 50 from both sides to isolate b)

  b    =   130

So, ∠b [angle b] = 130°

hope this helps! have a lovely day :)
