Suppose a line intersecting two lines a and b forms 35 degree angle with each line. what are the possible relationships between lines a and b?

you can conclude that lines A and B are parallel to each other

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

they charge the same amount at 20 minutes.
