Hey there!
In a rhombus, opposite angles are congruent. This means that 2y is equal to y+34. Let's set up an equation to solve for y.
2y=y+34
We subtract y from both sides.
y=34
Therefore, y=34°
I hope that this helps! Have a wonderful day!
It's goofy to subtract perimeter and area; they're in different units. We persist.
The area is
and the perimeter is
. so the difference is
