II
cos 75° + cos 15°​

Answer 1

Answer:

−5.025604

Step-by-step explanation:

sin(75)−(sin(1))(5)(cos(75))+cos(15)

=−0.387782−(sin(1))(5)(cos(75))+cos(15)

=−0.387782−(0.841471)(5)(cos(75))+cos(15)

=−0.387782−4.207355(cos(75))+cos(15)

=−0.387782−(4.207355)(0.921751)+cos(15)

=−0.387782−3.878135+cos(15)

=−4.265916+cos(15)

=−4.265916+−0.759688

=−5.025604
