The opposite angles are equal so m4=m1 and m2=m3. If you know m4=m1, m1= 138 so m4+m1= 276. That means m2 and m3 are equal to 84 in total. Your answer should be 48 for both m2 and m3 cuz they add to 84
What this question is asking, without all the wording, is what is 75% of 1400. You can easily find this by multiplying 1400 by 0.75. This will be your sales tax.

Sales Tax: $1050
2÷5=0.4 so by dividing 2 by 5 you would get 0.4
We are told that y varies directly with x.
Therefore
y = k*x
where
k = the constant of variation
The given table and the ratio of k=y/x is shown below.
x y k
--- ------ --------
6 10 1.667
9 15 1.667
12 20 1.667
15 25 1.667
Answer:
k = 1.667
y = 1.667x
