1.ABCD is a rectangle. its diagonals meet at O. lif AO = 5x-1 and BO = 4x+9.find the length of the diagonals.(lengths in cm)​

Step-by-step explanation:

Given

Required:

The length of the diagonal

Since AO and BO are diagonals that meets at O, we have:

This gives

Subsitute 10 for x in

The length of the diameter is:

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.
