Answer:
x=11
Explanation:
The inside(interior) angles of a triangle must add up to 180 degrees. A line is 180 degrees, so the angle GFH (the measure of the acute angle at point F) would be 180-(11x+1)
Now we have information on all 3 angles of the triangle; they must sum up to 180, so add all of these equations together
180-(11x+1) = 179-11x
Add this to 3x+19 and 70 gives 268-8x=180
Solving this equation for x we get -8x=180-268
-8x=-88
x=11
Hoped this helped and I hope you feel better!
