Based only on the information given in the diagram, which congruence theorems or postulates could be given as reasons why DEF=JK
NISA [10]

Answer:

A) AAS; B) LA; C) ASA

Step-by-step explanation:

AAS is the Angle-Angle-Side congruence statement.  It says that if two angles and a non-included side of one triangle are congruent to the corresponding two angles and non-included side of a second triangle, then the triangles are congruent.  In these triangles, ∠E≅∠K, ∠F≅∠L, and DE≅JK.  These are two angles and a non-included side; this is AAS.

LA is the leg-acute theorem.  It states that if a leg and acute angle of one triangle is congruent to the corresponding leg and acute angle of another triangle, then the triangles are congruent.

The leg we have congruent from each triangle is DE and JK.  We also have ∠E≅∠K and ∠F≅∠L, both pairs of which are acute.  This is the LA theorem.

ASA is the Angle-Side-Angle congruence statement.  It says that if two angles and an included side of one triangle are congruent to the corresponding two angles and included side of another triangle, then the triangles are congruent.  

We have that ∠D≅∠J, DE≅JK and ∠E≅∠K.  This gives us two angles and an included side, or ASA.

dybincka [34]

To draw the possible box make sure to follow the conditions required and organize the information.

<h3>What is a double box?</h3>

This is a type of chart that displays the data obtained by comparing two categories or elements. In this case, the goals of two different teams.

<h3>How to complete this task?</h3>

Read the prompt carefully.

Identify any conditions. For example, in this case, the number of goals obtained by the team warriors should be higher.

Organize the information in a chart.

Use the arc length formula and the given information to find r.. s = 16 cm, θ = 48°; r = ?
saveliy_v [14]

Answer:

The value for r is 19.1 cm

Step-by-step explanation:

We have been given that  s = 16 cm, θ = 48° and we have to find the radius r.

We know the relation

\theta=\frac{s}{r}\\\\r=\frac{s}{\theta},\text{ where }\theta \text{ is in radian}

Hence, first of all convert the angle in radian

θ = 48°= 0.837758 radian

Therefore, we have

r=\frac{16}{0.837758}\\\\r=19.1\text{ cm}
