Step-by-step explanation:
<h3>Part A</h3>
<u>Angle measures:</u>
- a = x = z = 51° (as vertical angles and corresponding angles)
- b = d = y = w = 180° - 51° = 129° (as supplementary angles and corresponding angles)
<h3>Part B</h3>
Supplementary angles for a linear pair and sum to 180°.
<u>Examples are:</u>
- a and b or
- a and d or
- x and y etc.

Answer:
e = -2
Step-by-step explanation:
9e - 7 = 7e - 11
9e - 7e = - 11 + 7
2e = -4
e = -2
Step-by-step explanation:
(31x-11)-15x=DF
DF= 16x-11
For thsi you need to think of 2 simulatneous equations=
16f + 28s= 24232
f + s = 1090
We need to find a way to subtract one equation from the other so you can multiply the bottom by 16
so you would get
16f + 28s = 24232
16f + 16s = 17440
Now you can subtract the second one from the bottom one to get
12s= 6792
s= 566
So there were 566 tickets sold on staurday so to find fridasy you can do 1090 -566, which is 524
so on friday night 524 were sold and on saturday there was 566 sold
