Answer:

<h2><u><em>x = -2</em></u></h2>

Step-by-step explanation:

15x+3x+19= -17 please help me find this answer

15x+3x+19= -17

18x + 19 = -17

18x = -19 - 17

18x = -36

x = -36 : 18

x = -2

---------------

check

15(-2)+3(-2)+19=-17

-30 - 6 + 19 = -17

-17=-17

the answer is good

X = 180 - 70 - 30 = 80 degrees.

X = 80
