Can you please help me

x = 75° and y = 105°

Step-by-step explanation:

In the given figure

∵ The angle of measure (180 - x) and the angle of measure y are

   corresponding angles

∵ Corresponding angles are equal in measures

→ Equate their measures

∴ 180 - x = y ⇒ (1)

∵ The angle of measure y and the angle of measure 75° are linear angles

∵ The sum of the measures of the linear angles is 180°

→ Add their measures and equate the sum by 180°

∴ y + 75 = 180

→ Subtract 75 from both sides to find y

∵ y + 75 - 75 = 180 - 75

∴ y = 105°

→ Substitute the value of y in (1)

∵ 180 - x = 105

→ Subtract 180 from both sides

∵ 180 - 180 - x = 105 - 180

∴ - x = - 75

∵ Divide both sides by -1 to find x

∴ x = 75°
