Question

I need help with properties of rhombus, rectangles and squares ​

Answer 1

• rhombus
• x = 70
• y = 5

Explanation:

A quadrilateral with 4 same-length sides is a rhombus.

(If the corner angles are also 90°, then the rhombus is also a square. That is not the case here.)

__

Adjacent angles are supplementary, so ...

x° = 180° -110° = 70°

Sides are the same length, so ...

2y = y+5

y = 5 . . . . . subtract y

_____

If part of the picture was cut off, the right side of the figure may be something other than 2y. If so, formulate the equation appropriately and solve for y.
