Answer:
"They add up to 180 degrees, because they are a pair of supplementary angles"
Step-by-step explanation:
When parallel lines are cut by transversal, it creates vertical angles (opposite of each other) that are equal AND also supplementary angles (that are adjacent to each other and fall in one line). They add up to 180 degrees.
Looking at the figure, we see angle 1 and 2 fall in one line which is 180 degrees. Thus, angles 1 and 2 are supplementary, they add up to 180 degrees.
The correct choice is "They add up to 180 degrees, because they are a pair of supplementary angles"
So do 3 * 3 equals 9 and do the same thing to the minutes. So 2 * 3 equals 6. So it takes 6 minutes for David to reach the 9th floor.
Also if that ^ ain’t correct, then here:
3/2 = 1.5 < minute per floor
1.5 * 9 < that’s the ninth floor
= 13.5
So it takes him 13.5 minutes to reach the ninth floor
Please don’t report me T.T I just gave you two answer in case on doesn’t work.
