Find the Value of the Unknowns X And Y In the Following Diagram: - 5 - Mathematics

Question

Find the value of the unknowns x and y in the following diagram:

Solution

y = 90° (Vertically opposite angles)

y = 180° (Angle sum property)

2x + y = 180°

2x + 90° = 180°

2x = 180° − 90° = 90°

x = `90^@/2 = 45^@`

  Is there an error in this question or solution?
