All internal angles in a quadrilateral add to 360
so
x+110+110+70=360
x+290=360
minus 290 both sides
x=70 degrees
If you want to show your work, you would need to do the problem yourself.

Answer: [a] 95% confidence interval = 4.4 < Ẍ <9.2
[b] margin of error = ± 2.4
Step-by-step explanation:
here let us carefully look into this problem,
from the question, we have that Ẍ = 6.8, and SE = 1.2
let us begin
(a). asked to calculate the 95% confidence interval we have;
95% C.I = Ẍ ± 2 (SE) = 6.8 ± 2(1.2) = 6.8 ± 2.4
95% C.I = (4.4, 9.2)
this gives the confidence interval to be (4.4 < Ẍ < 9.2).
(b). the error margin is ± 2.4, which implies that our estimate of 6.8 pounds is within 2.4 pounds of the true mean weight gain for the population.
cheers i hope this helped a great deal !!1
