The perimeter of a kite is 80 cm. If one side is 4 cm less than three times the other, find the length of each side

Step-by-step explanation:

let one side be x

and other side be 3x - 4

so perimeter = x + ( 3x - 4 ) + x + ( 3x - 4 )

80cm = 8x - 8

88cm = 8x

11cm = x

x = 11cm

3x - 4 = 3×11 -4

= 29cm

so sides are 11cm and 29cm

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.
