The base angles of an isosceles trapezoid are equal. Therefore:
20x + 9 = 14x + 15
6x = 6
x = 1
So, the base angles both equal 29 degrees.
In a trapezoid, the sum of the angles attached to the same leg always = 180 degrees.
Therefore, angle K and angle L equal 151 degrees.
The answer could be choice 1 or 3.
With direct variation, we simply multiply one variable to get the other variable.
In #1, we are multiplying t by 50.
In #3, we are multiplying t by r.
In both cases, t is just be multiplied by a number.
The correct answer is X=1
Divide by a whole number to get 40 which is 5 and then keep left over 3/8 to get mixed number of 5 3/8
Area of rectangle = 35 feet square
Let the Width of rectangle is x feet.
Length of rectangle is 3 feet more than twice the width.
Thus,Length can be written as: 2x + 3
Area of rectangle is product of its length and width.
So,
Area = Length x Width

Thus
x = -5
or
x =7/2 = 3.5
Since the measure of width cannot be negative, we neglect x = -5. and keep the value x = 3.5
Therefore,
Width = 3.5 feetLength = 2x + 3 = 2(3.5) + 3 = 10 feet
