Question

Measure of an angle of linear pair is 125°, then what is the measure of another angle=_______? Fill in the blank by selecting proper alternative.
(A) 55°
(B) 75°
(C) 65°
(D) 45°

Answer 1

measure of one angle is 125° and let the other angle be x and now

x + 125 = 180° ( Linear Pair)

x = 180 - 125

x = 55°

Measure of an angle of linear pair is 125°, then what is the measure of another angle= 55°

i.e. option A

Hope it helps!!

Answer 2

$\large{\red{\bold{YOUR ANSWER}}}$

As we know a linear pair means 180°

so given one angle = 125°

let the another angle be x

forming the equation as per the question

we get

125° +x° = 180°

x° = (180 - 125)°

x° =55°

So Option A) 55° is the right answer
