Trigonometry
Arc Length and Radian Measure
Solve the following problem.
Convert 75* to radians.

1.309 rad

Step-by-step explanation:

We are told to convert 75° to radians.

# we know that 1° is equivalent to 0.01745radians.

-To convert any angle degree to  radians, we multiply it by π/180 or 0.01745rad:

Hence, the radian equivalent of 75 is 1.309 rad

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

m=-16
