Vertical angles are equal to each other:
∠2 = ∠3
5 + 4y = 6y - 25
→ 30 = 2y
→ 15 = y
∠2 = 5 + 4y = 5 + 4(15) = 5 + 60 = 65
linear pairs equal 180:
∠1 + ∠2 = 180
→ ∠1 + 65 = 180
→ ∠1 = 115
The mean of a set of data is the average, so when writing a conclusion or justifying a solution, instead of listing all your data you can say "the average of the data collected was _____"
To find distance, subtract the largest number from smaller
41 - (-7)
41 + 7 = 48
the distance is 48
hope this helps
