5. Find the value of x.
6. Find the value of x.

Step-by-step explanation:

4. 2x+8+3x+5=123 (ext∠)

                  5x=110

                    x=22

5. 25+2x+3=3x-17 (ext∠)

                x= 45

6. 5x+2+6x+4=12x-4 (ext∠)

                    x= 10

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.
