Answer 1

Answer:

x = 55°

Step-by-step explanation:

If you observe a line is cutting two parallel lines and makes an acute and obtuse angles with each of them.

This acute angle made with first line must be equal acute angle made with second line because the lines are parallel lines.Similarly obtuse angles also must be equal.

From the given figure,

∠1 = ∠5  ( They are called corresponding angles)

2x - 15 = x + 40

⇒ x = 55°
