### Question

In the diagram what is x + y in terms of z?

### Options

A) 180o - z

B) 180o + z

C) z - 180o

D) z

The correct answer is A.

### Explanation:

x + y + z = 180(sum of angles in a $$\bigtriangleup$$)

x + y = 180 - z

## Dicussion (1)

• x + y + z = 180(sum of angles in a $$\bigtriangleup$$)

x + y = 180 - z
