Question

supplementry angle of 100 degree​

Answer 1

Answer:

80

Step-by-step explanation:

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

Now as per the definition 100+ unknown/supplementary angle  = 180°

lets take the unknown as= y

So, 100+ y = 180°

y= 180-100

y= 80°

So the supplementary of 100° is 80°

100+80= 180°
