What do you mean? I think you need to add a graph with the angles for people to be able to answer that question (you can take a screenshot and then use the paperclip button when you are re-writing the question). Hope this helped.
Answer:
104
Step-by-step explanation:
15 x 14= 210 divide by 2
105
180 - 105 = 75
15 + 14 + 75 = 104
<u><em>function </em></u>: p(x) = 65 + 25(x)
for 3 sells
for 10 sells
So,
140 ≤ p(x) ≤ 315
8.75 x 37.5= ? Well all you do is have to line up the decimals and work it out! :) it's simple
