Question

If two angels x and y are adjacent, state if their exterior arms are in a straight line when 1)x=110 and y=60

Answer 1

Answer:

Step-by-step explanation:

Answer:The correct answer is when x=102° and y=78°

Step-by-step explanation:

A straight line is equal to 180°

When x=110° and y=60°, x+y=110+60=170° Since x+y is not equal to 180°, exterior arms do not form a straight line.

Let's check the second case:

If x=102° and y=78°, x+y=102+78=180°

Since x+y is equal to 180° in this case, exterior arms form a straight line.
