Question

please give me the answer​

Answer 1

1) in a linear pair,the sum of angles is 180°

let the unknown angle be x

60°+x = 180

x= 180°-60°= 120°

2) same reason as above

x+ 135°= 180

x = 180 - 135 =45°

3) acute angle means an angle less than 90°

So the other angle will be an angle grater than 90°

So the other angle will be an obtuse angle.
