Answer 1

Answer:

20/3°

Step-by-step explanation:

this is a whole angle.

So, 4x+30+5x+10+6x+40=180°

=>15x+80=180°

=>15x=180-80

=>15x=100°

= x=100/15

=>20/3°

Answer 2

Answer:

4X + 30 + 6X + 40 + 5x - 10 = 180

15X + 60 = 180

15X = 180 - 60

15X = 120

X = 120/15

X = 8

8 is the correct answer of your question.
