Connelly has 1 / 4 of a cup of water. ryan has 2 / 5 of a cup of water. grayson has 0.4 less than 2 times connelly's amount of water.
write the expression that can be used to find how much water ryan and grayson have together.

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.

true !
