1.
1=87 corresponding angle.
2=180-87=93
2.
1=78 corresponding angles
2=78 verticle angles
3.
Set it up as (6x - 11) = 37
37 + 11 =48
6x = 48
x = 8
4.
Take 142 and see that it is supplementary to angle 2 so 180-142 = 38
38 is corresponding to the equation 2(x + 9)
So 2(x + 9) =38
Distributive property
2x + 18 = 38
38-18=20
2x =20
x = 10
Angle 2 is equal to 38 from supplementary to 142
I’m pretty positive about 1-3 but 4 maybe not be correct. But most likely these are correct

Step-by-step explanation:
The interquartile range is a measure that indicates the extent to which the central 50% of values within the data set are dispersed.
The interquartile range: Upper quartile - Lower quartile
As we can see in the box-and-whisker plots:
Class A: 89-66 = 23
Class B: 94-79 = 15
This shows that the spread in the scores of class A within the central 50% of values is higher than the spread of the scores of the class B.
Answer:
f(- 7) = - 57
Step-by-step explanation:
To evaluate f(- 7) substitute x = - 7 into f(x) = 7x - 8, since condition is
f(x) = 7x - 8 for x ≥ - 7, thus
f(- 7) = 7(- 7) - 8 = - 49 - 8 = - 57
Average speed = 5/2 = 2.5 km/h
