Answer:
1. Find < ACB
2. Use that triangles =180 to find <B = 41
Step-by-step explanation:
1.We need to find < ACB
<ACB +<DBC= 180 They make a straight line
Subtract DBC from each side
<ACB = 180 - <DBC
We know DCB = 113
ACB = 180 -113
ACB = 67
2.The three angles of a triangle = 180, so we can then find <B
<A +<B + <ACB = 180
72 + B + 67 = 180
Combine like terms
139+ <B = 180
Subtract 139 from each side
<B = 180-139
<B =41

Step-by-step explanation:
3 sisters bought 2 x 3 = 6 dress and and 1 x 3 = 3 purses.
3 sisters bought 6 dresses and and 3 purses.
Find 3 purses:
1 purse = $26
3 purses = $26 x 3 = $78
Find 6 dresses:
Total = $205.50
6 dresses = $205.5 - $78
6 dresses = $127.50
Find 1 dress:
6 dresses = $127.50
6 dresses = $127.50 ÷ 6
1 dress = $21.25
Answer: $21.25
