Question

if one pair of linear pair is an acute angle what kind of angle is the other

Answer 1

The other angle will be an obtuse angle, because only an obtuse angle can add up with an acute angle to form a linear pair.

Answer 2

it is the obtuse angled triangle. because one angle is acute . for eg- lets take acute angle as 80° and we know linear pair = 180° so to make 180° we have to add 80° + 100° . and 100° is obtuse angle
