Question

Which of the following pairs form a
supplement?
a. (3x + 110º) and (70° – 3x)​

Answer 1

Let take  (3x + 110º) as n and  (70° – 3x)​ as m.

Then,

⇒ n + m = 180°

(3x + 110º) + (70° – 3x)​ = 180°

3x - 3x + 110º + 70° = 180°

x + 180° = 180°

x = 180° - 180°

x = 0°

Therefore , now we know this suplmentary

beacause ,  180° = 180°

It is suplematary .

following pairs are supllementary.
