Does 5.5-7 equals -2.5 or -1.5?
show with steps/explain

it equals -1.5

Step-by-step explanation:

you take 7.0 and put the 5.5 under it you subtract and just change the sign to a negative since 7.0 is bigger does that make sense?

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.
