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

DIA [1.3K]

Answer:

The name of the quadrilateral is isosceles trapezoid.

Explanation:

1) The two parallel sides of different legths $1\frac{3}{4}$ and $1\frac{1}{4}$ 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.

Solve a-5/a+4 = 5/4 a=0 a=-1 a=-9 a=-40

umka21 [38]

Answer:

Step-by-step explanation:

we have

$a- \frac{5}{a} + 4 = \frac{5}{4}$

we multiple both sides by (4a)

$4a^{2} -20+ 16a= 5a\\4a^{2} + 11a - 20=0$

The delta = 11^2 - 4*4*(-20)= 121 + 320= 441= 21^2

These 2 solutions are:

$x_{1}=\frac{-11+ 21}{4*2} =\frac{10}{8} =\frac{5}{4} \\x_{2}=\frac{-11 - 21}{4*2} =\frac{- 32}{8} = - 4$

Solution: - 4 , 5/4

But maybe you wrote:

$\frac{a-5}{a+4}=\frac{5}{4} \\ 4(a-5)=5(a+4)\\4a -20= 5a+ 20\\4a-5a= 20 + 20\\-a = 40\\or\\ a= -40\\$

So a = -40

P.S: Pay attention to using parentheses
