As a result, in the parallelogram before, x = 4, Angle E = 104 degrees, and Angle EFH = 32 degrees.
What characteristics do parallelograms have?1. Opposing sides are congruent sides. ...
2. Opposing angles are congruent angles. ...
3. Interior angles that follow one another on the same side are supplementary. ...
4.Each of a parallelogram's diagonals divides it into two congruent triangles. ...
5. The diagonals of a parallelogram split in half.
As a result,
EH and FG's sides are parallel and equal.
so 3x=12
x=4
to determine Angle E
FGH Triangle
Angles FHG + HFG + G add up to 180.
(The total of a triangle's angles is 180)
FHG angle=180-44+104
=32
Angles EFH = FHG (alternate interior angles)
=32
Angle HFG = Angle EHF (alternate interior angles)
=44
Angle E=Angle HGF( opposite angles are equal in a parallelogram)
=104
Therefore the value of x in the given quadrilateral is 4 , the angle E is 104 degree and the value of Angle EFH is 32 degree.

Find the equation of the straight line passing through the point (0,-1) which is perpendicular to the line y=3/4x-3
Considering the definition of perpendicular line, the equation of the straight line passing through the point (0,-1) which is perpendicular to the line y=3/4x-3 is y= -4/3x -1.
Linear equationA linear equation o line can be expressed in the form y = mx + b
where
x and y are coordinates of a point.m is the slope.b is the ordinate to the origin and represents the coordinate of the point where the line crosses the y axis.Perpendicular linePerpendicular lines are lines that intersect at right angles or 90° angles. If you multiply the slopes of two perpendicular lines, you get –1.

Given, the rectangular garden is 5 ft longer than it's width.
The area of the garden is 300 ft.
dimensions of the garden are = ?
let the width be represented by x.
therefore, length = 5+x
area of the rectangle = l×w
substitute the values.
x(5+x) = 300
5x + x² = 300
x² + 5x - 300 = 0
x²+20x-15x-300 = 0
x(x+20)-15(x+20)=0
(x+20)-(x-15)=0
x=-20 or x=15
hence the dimension cannot be negative.

How do you determine whether to use plus or minus signs in the binomial factors of a trinomial of the form x^2 + bx + c where b and c may be positive or negative numbers?
The rule of signs in binomial factors given a trinomial in the form :
[tex]x^2\pm bx\pm c[/tex]Note that b and c can be positive or negative.
And the factor may be :
[tex](x\pm m)(x\pm n)[/tex]First thing to do is to check the sign of c.
If it is positive, the signs of m and n can be both positive or both negative.
Since positive multiplied by positive is positive and
negative multiplied by negative is also positive.
[tex]\begin{gathered} (+)\times(+)=+ \\ (-)\times(-)=+ \end{gathered}[/tex]If the sign of c is negative, one of the factors must be negative and the other must be positive, because negative multiplied by positive is negative.
[tex](-)\times(+)=-[/tex]After considering the sign of c, next to check is the sign of b.
Case 1 :
If b and c are both positive, we know that the factors can be both negative or both positive.
And since the sign of b is positive, we must follow the sign of it which is positive.
So both m and n are positive
For example :
[tex]x^2+5x+6[/tex]The factor will be :
[tex](x+2)(x+3)[/tex]which are both positive.
Case 2 :
If b is negative and c is positive, we will follow the sign of b. m and n will be both negative.
For example :
[tex]x^2-5x+6[/tex]The factors are :
[tex](x-2)(x-3)[/tex]which are both negative
Case 3 :
Now the third case is tricky.
If c is negative, we know that one of m and n is negative and the other one is positive.
The sign of the larger number between m and n will follow the sign of b.
For example :
[tex]x^2-x-6[/tex]c is negative, so one factor must be negative and the other must be positive. The sign of b is negative, so the larger factor must be negative also.
The factor will be :
[tex](x-3)(x+2)[/tex]3 is larger than 2, so the negative sign of b will proceed to the factor 3.

The equation of the line for the bike path is :
y = -5x - 15.
How to find the equation of a perpendicular line ?The original slope's reciprocal will be the opposite of the perpendicular slope. To find the intercept, b, enter the supplied point and the new slope into the slope-intercept form (y = mx + b). Rewrite the following equation in standard form: ax + by = c.Here :
Equation for the Lorne Lane line is y = -4/5x.
slope of the Eqe is -4/5
slope of the bike path perpendicular to Lorne Lane is -5/4
from the Graph point p is (-4, -10)
so
Equation of the line is y = -5x -15;
