Question

Solve for x in the diagram below.
(2 +40)
60°

Answer 1

`\boxed{x\degree = 20\degree}`

Explanation:

Vertically opposite angles are equal.

`= > (x + 40) \degree = 60 \degree \\ \\ = > x \degree + 40 \degree = 60 \degree \\ \\ = > x \degree = 60 \degree - 40 \degree \\ \\ = > x \degree = 20 \degree`

Answer 2

20°

Explanation:

x+40=60 (vertically opposite angle)

or, x=60-40

or, x=20°
