30o
150o
180o
60o
Correct Answer
(1) 30o
(2) 30o
(3) 150o
(4) 150o
Explanation
Work it out based on the measure of the straight line which is 180o.
You can find the measure of ∠x based on the straight line rule where x + 30o = 180o. Then use the vertical angles rule to find the value of ∠y where ∠y = ∠x because they are vertical angles, then ∠y = 150o.
