You’re going to need to add a picture to the problem it cannot be solved with just this information
Answer:
WY = 180
Step-by-step explanation:
the diagonals of an isosceles trapezoid are congruent , so
ZX = WY , that is
8y - 4 = 7y + 19 ( subtract 7y from both sides )
y - 4 = 19 ( add 4 to both sides )
y = 23
Then
WY = 7y + 19 = 7(23) + 19 = 161 + 19 = 180
The horizontal line has equation
. The line is solid, and everything below it is shaded, which translates to the inequality
. (so not B nor D)
The dashed line must have equation
. Because it's dashed, the inequality is strict. Pick any point in the shaded region, (0, 0) for instance, and compare both sides of this equation. (0, 0) means both
and
, so on the left side we have 0, and on the right we have -1. 0 > -1, so the inequality must be
.
This means the answer is A.
