Which line segment is drawn in the figure?

C) XZ is your best answer.

Step-by-step explanation:

Note that all the other choices are not line segments:

YZ is an arc segment, and is not your answer.

WY is also an arc segment, and is not your answer.

WZ is not a straight line, which does not make it a "line segment" (a straight line that is terminated on both ends by points).

step-by-step explanation:

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
