Answer:

x = 10

Step-by-step explanation:

Assuming you require the value of x

AB is a straight angle, thus the 3 given angles sum to 180°, that is

3x + 94 + x + 30 + 2x - 4 = 180, that is

6x + 120 = 180 ( subtract 120 from both sides )

6x = 60 ( divide both sides by 6 )

x = 10

Answer:

Step-by-step explanation:

all the angles on a straight line = 180.

so :

(3x+94)+(x+30)+(2x-4)=180

6x+120=180

6x=60

x=10

*substitute the value of x :

  • 3x+94

3(10)+94=124

  • x + 30

10+30=40

  • 2x-4

2(10)-4=16

*angle AOC = 124

*angle COD = 40

*angle DOB = 16
