Question

In the figure a pair of parallel lines are cut by a transversal. Find the value x.​

Answer 1

Answer:

x = 27°

Step-by-step explanation:

here one angle is supplementary of the other angle's alternate interior angle

As the alternate interior angles are equal, both the angles are supplementary to each other

So, 2x + 15° + 3x + 30° = 180°

=> 5x + 45° = 180°

=> 5x = 180° - 45°

=> x = 135°/5 = 27°
