A quadrilateral has one pair of parallel sides with lengths 1 3/4 inches and 1 1/4 inches, and two angles that measure 36 degree
s. What is the mane of the quadrilateral you drew?
1 answer:
Answer:
- <u><em>The name of the quadrilateral is</em></u><u> isosceles trapezoid.</u>
Explanation:
1) The two parallel sides of different legths and
constitute the bases of a trapezoid.
2) The two equal anglesare the base angles of the trapezoid, and mean that it is an isosceles trapezoid.
An isosceles trapezoid is truncated isosceles triangle.
The definition of trapezoid is a quadrilateral with at least two parallel sides.
The drawing is attached: only the green lines represent the figure, the dotted lines just show how this is derived from an isosceles triangle.

In order to solve for the value of 'x', we'll have to use cross-multiplication.
Cross-multiplication is a method in which the numerator of one fraction is multiplied by the denominator of another fraction that it is equal to.
Let's cross-mutliply the numerators and denominators:
=
9*(x+2) = 4*(3x)
Distribute the numbers into the parentheses.
9x + 18 = 12x
Simplify by subtracting both sides by 9x:
9x - 9x + 18 = 12x - 9x
0 + 18 = 3x
18 = 3x
3x = 18
Divide both sides by 3:
=
<u>x = 6</u>
