Aposter is 8 1/2 inches by 11 inches you enlarge the poster by increasing each dimension by a factor of 2 1/2 what is the area of the new poster

Area of the new poster = 584.375 inch²

Step-by-step explanation:

Length of old poster = 8 1/2 inches = 8.5 inches

Breadth of old poster = 11 inches

Scale factor = 2 1/2 = 2.5

Length of new poster =  8.5 x 2.5 = 21.25 inch

Breadth of new poster =  11 x 2.5 = 27.5 inch

Area of new poster = 21.25 x 27.5 = 584.375 inch²

Area of the new poster = 584.375 inch²

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.
