The graph below shows the total distance, in miles, traveled by a towboat over time, in hours. Which statement best describes the meaning of the coordinates of point F on the graph? *

m∠a is 90°

m∠b is 40°

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92

what are the

slope= 1

y-inter slope= 0

x       y

o     0

1       1

2     2

ect.
