Answer:
see below
Step-by-step explanation:
Opposite sides are parallel in a parallelogram, so if they have different slope, the figure will not be a parallelogram.
_____
<em>Comments on other answer choices</em>
If the slope of diagonal EG is perpendicular to that of diagonal FH, it only proves the figure is some sort of kite. The figure may or may not be a parallelogram.
Adjacent sides being different lengths does not prove anything (except that the figure is not a rhombus).
Proving angle F is a right angle does not prove anything else about the shape of the figure. The figure may or may not be a parallelogram. (If it is a parallelogram, it is also a rectangle.)
The value of y is 40 degree , Option B is the correct answer.
<h3>What is Angle Sum Property ?</h3>According to angle sum property, the sum of all angles of a triangle is equal to 180 degree.
It is given in the question a triangle , here
the angles given are 2y , y+10 , 50 degree
From the property ,
2y + y + 10 +50 = 180
3y +60 = 180
3y = 120
y = 40 degree
Therefore The value of y is 40 degree , Option B is the correct answer.

Answer:
Step-by-step explanation:
The square root property requires a quantity squared by itself on one side of the equation. The only quantity squared is x, so divide both sides by 2 before applying the square root property.
The x variable should be isolated on one side of the equation. The x variable is squared so before performing the square root property where we take the square root of both sides, we divide both sides by 2, then take the square root of both sides.
Dividing both sides by 2.
Taking the square root of both sides.
