Question

If the sum of two adjacent angles is 180' and one of them is 80°, then the other is.
{a} 70°
{b} 80°
{c) 90°
{d} 100​

Answer 1

Let the other angle be x
Now their sum =100
∘

⇒x+35
∘
=100
∘

⇒x=100
∘
−35
∘
=65
∘

So the other angle is 65
∘

Answer 2

Answer:

100 degree

Step-by-step explanation:

sum of two adjacent angle180

one angle is 80 degree

therefore other angle = 180 - 80 = 100
