Answer:
y = 10
Step-by-step explanation:
The opposite sides of a parallelogram are congruent, hence
x + 10 = 110 - 4x ( add 4x to both sides )
5x + 10 = 110 ( subtract 10 from both sides )
5x = 100 ( divide both sides by 5 )
x = 20
Using the other pair of congruent sides, then
3y - 10 = 2x - 20 = (2 × 20) - 20 = 40 - 20 = 20, thus
3y - 10 = 20 ( add 10 to both sides )
3y = 30 ( divide both sides by 3 )
y = 10

You can make use of either or both of these rules of exponents:
(a^b)^c = a^(b·c) . . . . . used above
![\sqrt[n]{a}=a^{\frac{1}{n}}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%7D%3Da%5E%7B%5Cfrac%7B1%7D%7Bn%7D%7D)
Using the second rule, you can write the expression as ...
