Respuesta :

5: 25 degrees
8: 48 degrees

Still working on the other ones

Explanation
- for 5 we know that the straight line has a measurement of 180 degrees so we just add 125 and 30 to get 155 and 155 plus 25 is 180 degrees

- For 8 we know that the measurements of AED are 89 degrees and we know two other angles are 29 and 12 which make 41 if you add them and we know that 41 + 48= 89 which is what we wanted to get to

Answer:

5. X=25

6. X=20

8. X=48

9. X=44

Step-by-step explanation:

5) 180 - (125+30)

X= 25

6) 6x = 120

X = 120/6

X= 20

8) 89 - (29 + 12)

X= 48

9) (3x+30) = 162

X = (162-30)/3

X = 44
