$\bf \begin{array}{ccll} ft^2&minute\\ \cline{1-2} 50&\frac{1}{5}\\\\ x&6 \end{array}\implies \cfrac{50}{x}=\cfrac{~~\frac{1}{5}~~}{6}\implies \cfrac{50}{x}=\cfrac{~~\frac{1}{5}~~}{\frac{6}{1}}\implies \cfrac{50}{x}=\cfrac{1}{5}\cdot \cfrac{1}{6} \\\\\\ \cfrac{50}{x}=\cfrac{1}{30}\implies 1500=x$

Answer:

60 square feet.

Step-by-step explanation:

Given : a water pipe leak floods 50 square feet every 1/5 minute.

To find : what is the flooded area after 6 minutes.

Solution : We have given

In $\frac{1}{5}$ minute water pipe leak flood = 50 square feet.

In 1 minute water pipe leak flood = 50 * $\frac{1}{5]$ .

In 1 minute water pipe leak flood = 50 * $\frac{1}{5}$ * 6 square feet.

In 1 minute water pipe leak flood = 10 * 6 square feet.

In 1 minute water pipe leak flood = 60 square feet.

Therefore,

60 square feet.

Which method would you use to prove that the two triangles are congruent?

Alona [7]

Answer:- AAS postulate

Explanation:-

AAS postulate tells that if two angles and a non-included side of a triangle to equal to the two angles and a non-included side of another triangle then the two triangles are said to be congruent.

Given:- One angle and one side of a triangle is equal to the one angle and one side of the other triangle.

We see there is one more pair of equal angles as they are vertically opposite angles . [See the attachment]

⇒ there is a triangle where two angles and a non-included side of a triangle to equal to the two angles and a non-included side of another triangle then the two triangles are said to be congruent.

⇒ The triangles are congruent [ by ASA postulate]
