Answer:
Hank is correct
Step-by-step explanation:
With parallel lines intersected by the same line, all corresponding angles are equal. Also remember that the two angles the are formed on each line need to add to 180 degrees. So we can take the two given angle: 7x+10 and x + 10 and add them. x + 10 + 7x + 10 = 8x + 20 = 180
So Hank has the correct equation.
Answer:
All real numbers except the number zero
Step-by-step explanation:
we know that
Observing the graph
The range is the interval
(-∞,0) U (0,∞)
The number zero is not included in the range
therefore
All real numbers except the number zero
The sum of the angles in a heptagon is 900°, so we would add the real numbers that we have here:
121°+139°+125°+126°+158°+120°=789°
x would equal the remaining value:
x=900-789
x=111°
-4 I'm not 100% but I think this is the answer
