Answer: The correct option is:

(D) It is a trapezoid because it has exactly one pair of opposite sides that is parallel.

Step-by-step explanation: We are given to select the statement that best describes the structure outlined in the bridge.

The definitions of a parallelogram and a trapezoid are as follows:

PARALLELOGRAM: A Parallelogram is a quadrilateral having opposite sides parallel and congruent.

TRAPEZOID: A trapezoid is a quadrilateral having one pair of opposite sides parallel.

We can see in the given figure,

the structure outlined in the bridge has only one pair of opposite sides parallel.

So, it must be a TRAPEZOID.

Therefore, the given structure is a trapezoid because it has exactly one pair of opposite sides that is parallel.

Thus, (D) is the correct option.

Let D be the Intersection of Height of the Triangle and Base of the Triangle BC

From the Figure, We can notice that Triangle ADB is a Right angled Triangle.

We know that, In a Right angled Triangle :

$\bigstar$ (Hypotenuse)² = (First Leg)² + (Second leg)²

In Triangle, ADB : AB is the Hypotenuse, AD is the First leg and BD is the Second leg

Given : AB = 15 and BD = 9

Substituting the values, We get :

$:\implies$ (15)² = (AD)² + (9)²

$:\implies$ 225 = (AD)² + 81

$:\implies$ (AD)² = 225 - 81

$:\implies$ (AD)² = 144

$:\implies$ (AD)² = (12)²

$:\implies$ AD = 12

We know that, In a Right angled Triangle :

$\bigstar\;\;\boxed{\mathsf{Tan\theta = \dfrac{Opposite\;Side}{Adjacent\;Side}}}$

Now, Consider Triangle ADC : With respect to 45° Angle, AD is the Opposite Side and DC is the Adjacent Side

$:\implies \mathsf{In\;Triangle\;ADC,\;Tan45^{\circ} = \dfrac{AD}{DC}}$

$\mathsf{:\implies 1 = \dfrac{12}{DC}}$

$:\implies$ DC = 12

$:\implies$ Total Length of the Base (BC) = BD + DC

$:\implies$ Total Length of the Base (BC) = 9 + 12

$:\implies$ Total Length of the Base (BC) = 21

We know that, Area of the Triangle is given by :

$\bigstar\;\;\boxed{\mathsf{Area = \dfrac{1}{2} \times Base \times Height}}$

In Triangle, ABC : AD is the Height and BC is the Base

$:\implies \mathsf{Area\;of\;the\;Triangle\;ABC = \dfrac{1}{2} \times BC \times AD}$

$:\implies \mathsf{Area\;of\;the\;Triangle\;ABC = \dfrac{1}{2} \times 21 \times 12}$

$:\implies \mathsf{Area\;of\;the\;Triangle\;ABC = (21 \times 6)}$

$:\implies \mathsf{Area\;of\;the\;Triangle\;ABC = 126}$

marshall27 [118]

Answer:

8 scoops of flour

Step-by-step explanation:

Set up a proportion so,

(5/25)=(x/40) *Solve for X*

25x = 200

x = 8

Please Help 6th Grade Math! Box Plots! 2 questions (Image attached)

tangare [24]

Answer:

First answer is 14

Second answer is 25

Step-by-step explanation:

Median is the middle ( 1 2 3 4 5 the median would be 3)

You start at 2 and end at 27

List all the numbers from 2 to 27 and come from both ends until you get to the middle number(s)

In this case there are two 14 & 15

14+15=29 29÷2=14.5

Since there are no decimal answers you are left with 14

Range you take the two end numbers and subtract them (27 & 2)

27-2=25

Hopefully this helps!
