If you want to stop the current flow through device 3 in the circuit shown above, which one of the following single switches should you open?

a. switch s2
b. switch s4
c. switch s3
d. switch s5- right
hope this hell someone out . the answer is d

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

14

step-by-step explanation:

14 x 3 = 42
