Answer:
x = 27
Step-by-step explanation:
Since AC and DE are parallel lines, then
∠ BAD = ∠ EDF= 2x ( corresponding angles )
The sum of the 3 angles in Δ BAD = 180°, thus
2x + 2x + 72 = 180, that is
4x + 72 = 180 ( subtract 72 from both sides )
4x = 108 ( divide both sides by 4 )
x = 27
Y=13
(when you have fractions like the one in this problem, you get rid of them by multiplying both sides by the denominator.)
Root3 would be between 1 and 2 on the number line. This is known because 1 squared is 1, and 2 squared is 4.
