Answer 1

Hey mate!!!

(a) We know that sum of a linear pair is 180°
and we also know that acute angle is less than 90° that is <90°

So other angle = 180° -< 90°
Here we assume the acute angle is 89° as it is the greatest acute angle, so
180° -89° = 91°
and angles gelreater than 90° is obtuse angle.
Event if we take smallest acute angle that is 1
we will get other angle = 180° - 1 = 179°
and angles smaller than 180° but greater than 90° are obtuse.


So your answer is obtuse angle

b) Here we have to reverse the upper method.
Greatest obtuse angle = 179°
other angle = 180 - 179 = 1°
and1 is acute angle
Smallest obtuse angle is 91°
and 180- 91 = 89
which is also an acute angle.


So we have your answer - Acute angle


c) A right angle is always of 90°
so other angle = 180 - 90 = 90°
which is also a right angle

So your answer is a right angle.


Hope it helps dear friend ☺️✌️✌️
