Your company takes orders over the phone. the company’s average call time is 4.6 minutes. the graph below shows 4 calls and the difference between the call time and the company’s average call time. for these 4 calls, what is the mean difference between the call times and the company’s average call time, rounded to the nearest 0.1 minute?

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

this is false ^.^ lol
