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· = 180°            ( - From (1) )
πβ πππ· = 180Β° - 150Β°
= 30Β°
Hence Proved.
