#### Question

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

#### Solution

*y* = 90° (Vertically opposite angles)

*x *+ *x *+ *y* = 180° (Angle sum property)

2*x* + *y* = 180°

2*x* + 90° = 180°

2*x* = 180° − 90° = 90°

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

Is there an error in this question or solution?
