Question

(i) Two angles measure (30° - x) and (125° + 2x). If each angle is the supplement of the
other, find the angles.​

Answer 1

Answer:

30-x+125+2x=180

x=25.

Answer 2

two angles measure is always 180degree called supplementary angle

so 30°-x + 125°-2x=. 180

30+125-x-2x. =180

155-3x=180

-3x =180-155

-3x. =25

X=25/-3

X=8.3
