Question

If one angle in a linear pair is obtuse then the other one is what?

Answer 1

Answer:

The other angle is an acute angle.

Explanation:

Let the two angles be x and y.

In a linear pair of angles, the sum of the angles is 180°. So, if one of the angles is an obtuse angle, it is greater than 90.

let x > 90°,

now,

x + y = 180°

y = 180° - x

But, since x > 90°,

when it is subtracted from 180, the result will be less than 90°,

hence,

y < 90° or y is an acute angle.

Answer 2

Answer:

X=180,X+X=180,2X=180,180\2=90

The type of other angle is 90
