Which ordered pair is a reflection of (3,7) across the x-axis? O (-3,-7)
O (-3,7)
O (7-3)
O (3,-7)

(3,-7)

Step-by-step explanation:

Using the algebraic rule for Rx-axis

(x,y)>(x,-y)

(3,7)--->(3,-7)

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.
