1) Point O is between points A and B, find AB =? Draw. AO = x + 3
OB = 2x - 1
AB = x + 14

A) 9

B) 11

C) 20

D) none

c

Step-by-step explanation:

x+3+2x-1=AB

x+3+2x-1=x+14

3x+2=x+14

2x=12

x=6

6+14=20

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.
