Question

# Use the given information and the diagram to prove the statement.

Given: πβ πππΆ + πβ πππ· = 180Β° and πβ πππΆ = 150Β°

Prove: πβ πππ· = 30Β°

Hint:

### Use the information given.

## The correct answer is:

### SOL β It is given that πβ πππΆ = 150Β° Β Β Β ---- (1)

πβ πππΆ + πβ πππ· = 180Β°

150Β° + πβ πππ· = 180Β°Β Β Β Β Β Β Β Β Β Β Β Β ( - From (1) )

πβ πππ· = 180Β° - 150Β°

= 30Β°

Hence Proved.
