ANSWER:
x = 55°
The value of 'x' is equivalent to 55°.
STEP-BY-STEP EXPLANATION:
The rhombus in the rectangle is a regular rhombus. It has two pairs of parralell sides.
Therefore, we can use co-interior angles on parallel lines to solve this problem. Co-interior angles are two angles on parallel lines which form a 'C' shape and add up to 180°.
THEREFORE:
( 2x + 20 )° + ( 50 )° = 180°
2x = 180 - 20 - 50
2x = 110
x = 110 / 2
x = 55°
Answer:
A form of blocking by three variables.
Step-by-step explanation:
Graeco-Latin square design is a special type of comparative design.
Graeco-Latin square design uses 3 blocking variables unlike the 2 blocking variable as used by the standard Latin square design.
In this square design of experiment, the experimental units are grouped into three different ways.

From the second:
2x-y=4
x=(4+y)/2 and applying this to first:
4+y+3y=12
4y+4=12
4y=8
y=2 and since x=(4+y)/2, x=3 so
x+y=2+3=5
