Is 5 1/2% is also written as 5.5%.??

Yes. 5 1/2% is also written as 5.5%.

Step-by-step explanation:

5 1/2% = 5.5 %

1/2 = 1 : 2 = 0.5

5 1/2%

= 5.0 + 0.5 %

= 5.5 %

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.
