Answer: 15 feet

Step-by-step explanation:

Given: Quadrilateral ABCD is similar to quadrilateral EFGH.

If the two shortest sides of quadrilateral EFGH are 6 feet long and 12 feet long.

Let x be the shortest side of quadrilateral ABCD .

The measurement of sides of  quadrilateral ABCD arranged in order :-

60 feet , 40 feet, 30 feet and x feet.

We know that the corresponding sides of two similar polygons are proportional.

⇒ The two shortest sides of quadrilateral ABCD is proportional to the two proportional sides of quadrilateral EFGH.

⇒\dfrac{6}{12}=\dfrac{x}{30}\\\\\Rightarrow\ x=\dfrac{30\times6}{12}=15

Hence, the length of the 4th sides of quadrilateral ABCD = 15 feet.

Please help asap !!!!!! what vaule of x makes the equation true 3(x-4)=15
DaniilM [7]

3(x-4) = 15

Distribute the 3:

3x-12 = 15

Add 12 to both sides:

3x = 27

Divide both sides by 3:

X = 9

The answer is D. 9

Conver the equation y=2 to polar form. Then solve the resulting equation for r. <br> Thanks :)
maksim [4K]
This is something to memorize

y = r*sin(theta)

so if y = 2, then 

2 = r*sin(theta)

Divide both sides by sin(theta) to get

r = 2/sin(theta)
r = 2csc(theta)
