3y - x = 21

Step-by-step explanation:

y = -3x - 8

The perpendicular line has the reciprocal slope.

So, the slope of this perpendicular line would be 1/3.

The equation that has the slope of 1/3 is 3y - x = 21.

Hope this helps!

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.

answer: 48
