Answer:

A is the right answer

Step-by-step explanation:

Answer:

266

Step-by-step explanation:

Answer:

A = 1/2bh

= 1/2 x 10 x 24

= 120

Answer:

See Below.

Step-by-step explanation:

Let the intersection point above E be K, and let the intersection point below E be J.

Since ABCD is a trapezoid:

[tex]\displaystyle AB\parallel DC[/tex]

Therefore:

[tex]\displaystyle \angle AJF\cong \angle DKF[/tex]

And:

[tex]\displaystyle \angle DFJ\cong \angle DFJ[/tex]

So, by AA-Similarity:

[tex]\displaystyle \Delta DFK\sim \Delta AFJ[/tex]

CPSTP (Corresponding Parts of Similar Triangles are Proportional):

[tex]\displaystyle \frac{KD}{JA}=\frac{FK}{FJ}[/tex]

Likewise, do the same to the other side. Since AB is parallel to DC:

[tex]\displaystyle \angle BJF\cong CKF\text{ and } \angle CFJ\cong \angle CFJ[/tex]

Hence:

[tex]\Delta CFK\sim \Delta BFJ[/tex]

By CPSTP:

[tex]\displaystyle \frac{KC}{JB}=\frac{FK}{FJ}[/tex]

Substitution:

[tex]\displaystyle \frac{KD}{JA}=\frac{KC}{JB}[/tex]

Since AB is parallel to DC:

[tex]\displaystyle \angle CDB\cong \angle ABD[/tex]

By vertical angles:

[tex]\angle DEK\cong BEJ[/tex]

Hence, by AA-Similarity:

[tex]\Delta DKE\sim \Delta BJE[/tex]

CPSTP:

[tex]\displaystyle \frac{KD}{JB}=\frac{KE}{JE}[/tex]

Likewise:

[tex]\angle DCE\cong \angle BAC[/tex]

And by vertical angles:

[tex]\displaystyle \angle CEK\cong \angle AEJ[/tex]

Hence:

[tex]\Delta CKE\sim \Delta AJE[/tex]

CPSTP:

[tex]\displaystyle \frac{KC}{JA}=\frac{KE}{JE}[/tex]

Substitution:

[tex]\displaystyle \frac{KD}{JB}=\frac{KC}{JA}[/tex]

Now, we have obtained that:

[tex]\displaystyle \frac{KD}{JA}=\frac{KC}{JB}[/tex]

And:

[tex]\displaystyle \frac{KD}{JB}=\frac{KC}{JA}[/tex]

In the second proportion, multiply both sides by JA:

[tex]\displaystyle \frac{KD\cdot JA}{JB}=KC[/tex]

In the first equation, multiply both sides by JB:

[tex]\displaystyle \frac{KD\cdot JB}{JA}=KC[/tex]

Substitute:

[tex]\displaystyle \frac{KD\cdot JA}{JB}=\frac{KD\cdot JB}{JA}[/tex]

Cross-multiply:

[tex]JB\cdot KD\cdot JB=JA \cdot KD\cdot JA[/tex]

Cancel out KD and simplify:

[tex]JB^2=JA^2[/tex]

Therefore:

[tex]JB=JA[/tex]

And using the first proportion again:

[tex]\displaystyle \frac{KD}{JA}=\frac{KC}{JA}\Rightarrow KD=KC[/tex]

Hence, EF bisects AB and DC, the bases of the trapezoid.

Answer:

the amount of money that you are charged

Step-by-step explanation:

the dependent variable is defined as a variable which changes depending on the other variables that are manipulated in a function so what that means is that the inputs are independent variables and the outputs are the dependent variables and in the case of this question the amount of texts sent are the independent variables and the amount charged is the dependent variable

Answer:

The Answer is 0.9!!!!!!!!!!!!!

Answer:

0.9

Step-by-step explanation:

Converting the fraction 18/20 to a decimal is 0.9

1st Method: Simplify

18/20 can be simplified to 9/10. 9/10 is equivalent to 0.9

2nd Method: Use long division

Convert the fraction to a decimal by dividing the numerator by the denominator.

Answer:

isosceles triangle

Step-by-step explanation:

Explanation:

Vertical angles form when we have an X shape like this. They are opposite one another and always congruent. Angles 2 and 4 is the other set of vertical angles.

Answer:

B. 1 & 3

Step-by-step explanation:

The vertical angles are pairs of opposite angles made by 2 intersecting lines. Here, 1 and 3 are the same length, and are on opposite sides.

Answer:

x+6<12

Step-by-step explanation:

Since it is going left from 6, we know that x must be less than 6

(if u need me to explain more I can)

Answer:

It is the third option

going left from 6, we  can see  that x must be less than 6

Answer:

He should have multiplied 15 tsp by 1 tbsp/3tsp.

Step-by-step explanation:

The tsp labels cancel each other out when one is the numerator and one is the denominator.

15tsp x 1 tbsp/3tsp = 15/3 = 5 tbsp

Answer:

3⋅120=360

Step-by-step explanation:

$120 multiplied by 3

Answer:

60°

Step-by-step explanation:

Since this is an equilateral triangle all the angles and sides are the same.

180÷3=60°

All the angLes will be 60°, because in a triangle ball angles must add up to 180°.

Hope this answers your question.

Answer:

b = 42° and c = 180-42 = 138°

Answer:

b) 42°

c) 138°

Step-by-step explanation:

Get 42° by looking at its vertical partner(vertical angle). Get 138° by subtracting 42 from it. Subtract 42 from the sum of the entire angle, and get 180° degrees.

Hope this helps! Have a wonderful rest of your day!
