Erica needs 5 and one half gallons of paint to paint the house. she has 3 and one half gallons at school, and a friend can give her another 1 and three fourths gallons. how much more paint does she need?

3x3 = 9 and 2x2 = 4

step-by-step explanation:

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.
