The answer is:103
7 goes into 7 once, then you subtract 7 from 7 which is zero. Bring down the 2 and it goes in 0 times, so you put zero on top and subtract, bring down the 1 then you get 21, which goes in 3 times.
Hope it helps!!

Answer:
80
Step-by-step explanation:
in the figure above, angle 100 degrees is corresponding to the angle co - interior to angle x
that is
if we put an angle that is at the upper left of x, we can call that y which is corresponding to 100 degrees
since y is corresponding to 100 degrees, it automatically becomes the same as 100 degrees
therefore y=100
now, from the first line above, we know that x and y are co-interior which means that they both add up to 180 degrees
that is
x+y=180
we know that y = 100
therefore,
x+100=180
collect like terms and
x = 180-100
therefore,
x= 80
