Question

A same side interior angle of two parallel lines is three times the other same side interior angle. Find the measures of these two angles.

Answer 1

45 , 135

Explanation:

As we know the property of interior angle if there are two parallel lines i.e The sum of two angle is 180.

Let the First angle be x then other angle 3x

So

x + 3x= 180 [ By the interior property the sum of two angle is 180]

4x=180

`x=\ (180)/(4) \\x=45`

Therefore Other angle is 3*45= 135
