Answer:
x = 16
y = 131
Step-by-step explanation:
4x + 2x - 6 = 90
6x = 96
x = 16
16 + 33 + y = 180
49 + y = 180
y = 131
She would have a total of 40 stamps.
There is 75% decrease.

Decrease percent =
Decrease percent =
Decrease percent =
Decrease percent = 75%
There is 75% decrease.

Answer:
If the interior angles of quadrilaterals STUV and WXYZ are equal then the quadrilaterals, STUV and WXYZ were similar.
Step-by-step explanation:
Quadrilaterals are polygons with four sides.
Similar polygons are in identical form, but can be variant magnitudes.
Two polygons can be considered as similar if the following two things are accurate:
1. The corresponding sides of each polygon are in the same proportion
2. The corresponding interior angles are the equal (congruent).
So, if the interior angles of quadrilaterals STUV and WXYZ are equal then the quadrilaterals, STUV and WXYZ were similar.
X= 23 im pretty sure hope this helps best of luck :)
