Add Four-sevenths plus two-sevenths. What is the sum in lowest terms?

You are correct, the answer is 6/7

Step-by-step explanation:

4 + 2 = 6

so, 4/7 + 2/7 = 6/7

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.

109 is the nearest whole number/final answer! : )
