Answer:

Step-by-step explanation:

They're asking for what other information is needed.

We were given triangle ABC is congruent to triangle DEF. We know for certain line AB and line DC are congruent to each other as well as lines BC and EF.

The additional information we need to know is if line AC is congruent to line DF to absolutely be sure.

Remember SSS by definition is: Triangles are congruent if all three sides in one triangle are congruent to the corresponding sides in the other. If all three sides in one triangle are the same length as the corresponding sides in the other, then the triangles are congruent.

The area of circular garden is 615.44 feet2. What is the circumference of the garden? (Use 3.14 for .)

ella [17]

Answer:

B.)

87.92 feet

Step-by-step explanation:

Given:

Area of the circular garden $= 615.44 ft^2$

$\pi =3.14$

Finding the radius of the circle.

Area of the circle= $\pi r^2$

$615.44=\pi *r^2$

$r^2=\frac{615.44}{\pi } \\\\r^2=\frac{615.44}{3.14} \\r^2=196\\r=14 ft.$

Circumference of the garden:

$=2\pi r\\=2*3.14*14\\=87.92ft.$

7. How many different ways can a class of 22 second graders line up to go to lunch?

pogonyaev

Answer:

The number of different ways are 22! or 1,124,000,727,777,607,680,000.

Step-by-step explanation:

Consider the provided information.

We need to determine the number of different ways can a class of 22 second graders line up.

We need to select 22 second graders while taking 22 at a time.

So use the permutation formula: $^{n}P_{n}$

Substitute n=22 and simplify.

$^{22}P_{22}=\frac{22!}{(22-22)!}\\22!=1,124,000,727,777,607,680,000$

Hence, the number of different ways are 22! or 1,124,000,727,777,607,680,000.

How are these triangles congruent ? <br> - HL <br> - AAA<br> - ASA

agasfer [191]

Answer:

Congruent by AAA

Step-by-step explanation:

Given

$\triangle MNP$

$\triangle QST$

Required

The congruence rule

From the attached triangles, we have:

$\angle M = \angle Q$ --- A

$\angle N = \angle S$ --- A

$\angle P = \angle T$ --- A

<em>Hence, the congruence rule is AAA</em>
