Question

what is the supplementary angle of 130 degree​

Answer 1

Answer:

50°

Step-by-step explanation:

A supplementary angle is  where either of two angles whose sum is 180°.

130°+ unknown/supplementary angle = 180°

lets take unknown as x.

130°+ x= 180

x= 180°-130°

x= 50°

130+50=180°

50° is the supplementary of 130°
