A quilt is designed using a square pattern. Each square contains two rectangles. Each rectangle contains a shaded rhombus.
2 answers:
The sum of angles in any Rhombus is 360 degrees.Opposite angles of a rhombus are congruent.
Two of the adjacent angles are 2x+20 and 50 degrees.
The opposite angles measure 2x+20 and 50 degrees.
Sum of angles in any Rectangle is 360
2x+20+50+2x+20+50=360
Adding line terms,
4x+140=360
Subtracting 140 both sides:
4x=220
Dividing both sides by 4
x=55
Option B. 55 is the right answer.
The 4 angles of a rhombus should add up to be 360 degrees.
So,........................... 2x + 20 + 2x + 20 + 50 +50 = 360
Combine like terms:............................... 4x + 140 = 360
Subtract 140 from both sides ..........................4x = 220
Divide by 4.............................................................. x = 55
