Answer:
can u give more information about the problem, like what are the options?
Step-by-step explanation:
Answer:X= 10.1
Angle answer is correct
Step-by-step explanation: 7X+1+108.3=180
7X+109.3=180
-109.3
7X= 70.7
Divide by 7
X = 10.1
This equation is written in point-slope form (y-y1)=m(x-x2). Since the variable m always represents slope in basic mathematics then the slope is 5.
First divide both sides by 2 so that we can get rid of the parentheses, so we get

now subtract 5 from both sides

then finally we want x alone so we'll divide both sides by 3 and get our final answer!
