SUM OF SUPPLEMENTARY ANGLE IS 180°.

LET THE FIRST ANGLE BE 'X'.

HENCE,

ACCORDING TO THE QUESTION,

SECOND ANGLE WILL BE ('X' + 80°).

ALSO (X+80°)+(X) = 180°.

2X +80° = 180°.

2X = 180°-80°

2X= 100°

X=   100/2

X = 50°

HENCE FIRST ANGLE WILL BE 50°AND SECOND ANGLE WILL BE 50+80 = 130°.

Answer 2

Answer:

Step-by-step explanation:

supplementary angles add up to 180°

let the other angle be y

23°+y=180°

y=180°-23°

y=157°

therefore the other angle is 157°
