Answer:
Triangle ABC is congruent to DCE by SAS Theorem.
Step-by-step explanation:
Since AB is parallel to DC, we can say that BC is congruent to CE and AC is congruent to DE, then:
If two sides in one triangle are congruent to two sides of a second triangle, and also if the included angles are congruent, then the triangle is congruent.
Triangle ABC is congruent to DCE by SAS Theorem.

Answer:
x = {x: -1, 5}
Step-by-step explanation:
[tex]{ \rm{f(m) = (x + 1)(x - 5)}}[/tex]
- To find the values of function f(m), we consider its zero or its root by letting f(m) = 0

- Either (x + 1) or (x - 5) is equated to zero

For (x - 5);[tex]{ \rm{x - 5 = 0}} \\ { \rm{x = 5}}[/tex]

12. How many centimeters are there in 740.2millimeters?A 7402 cm© 7.402 cmB 74.02 cmD 0.7402 cm
Answers
In this kind of question, we always need to know what is the equivalence between two measures:
We already know that in 1 centimeter there are 10 millimeters. With this equivalence, we can write:
740.2 millimeters * ( 1 centimeter / 10 millimeters )
When we have a unit in the numerator and also in the denominator, like millimeters, in this case, both units are converted in 1, and they do not need to be in the final answer (millimeters/millimeters = 1). Therefore:
740.2 * ( 1 centimeter / 10 ) =
( 740.2 / 10 ) centimeter =
When we divide a number by 10, 100, 1000, we write the decimal point to the left as many zeros have the 10, 100, 1000. In this case, we only have one zero.
Thus, we write the decimal part one digit to the left:
( 740.2 / 10 ) centimeter =
74.02 centimeter (this is the answer).
Therefore, there are 74.02 centimeters in 740.2 millimeters.

The value of the angle x will be equal to 113.5°.
An angle may be defined as the figure which can be formed from two rays joining at a point. The lines will be called as the sides of the angle and the point at which the rays join is called vertex of the angle. There are generally 5 types of angles namely Acute angle, Obtuse angle, Reflex angle, Right angle and Complete angle. The value of a complete angle will be given as 360°. Since, in the question all the angles are measured to the nearest. So, the value of 59° could actually be something between 58.5° and 59.5°. Analogously, 108° is between 107.5° and 108.5°, and 81° is between 80.5° and 81.5°. Now, the summation of all four angles will be equal to 360°.
x + 58.5° + 107.5° + 80.5° = 360°
=> x = 360° - (58.5° + 107.5° + 80.5°)
=> x = 360° - 246.5°
=> x = 113.5° which is the required value.

A battery is charged. The percentage of the battery's capacity that is charged as a function of time (in minutes) is graphed 50+ 70 50+ Capacity charge 20+ 10 What was the battery's charging level when the charging began? 12
Answers
The equation of the line (segment) is:
[tex]y=2x+40[/tex]Where y is the percentage of the charge, and x is the time (in minutes) that has passed since the charge started.
How do we know that? Because we can identify two points in the graph shown in the image:
[tex](0,40),(5,50)[/tex]
Notice that the line intersects the y-axis in point 40 (when the battery had 40% of its charge)
You can easily see that the equation I first wrote is correct by simply substituting the values of those two points I just wrote above.
Since we need 'the battery's charging level when the charging began', we need to set x=0, as we need the value of y (percentage of the charge) when the charging started.
So, if x=, then:

Let us first solve the triangle on the right side involving angle x.
Recall that the sum of angles in a triangle must be equal to 180°.
So we can write
[tex]\begin{gathered} 41+78+x=180 \\ 119+x=180 \\ x=180-119 \\ x=61\degree \end{gathered}[/tex]Therefore, the angle x is equal to 61°
Now let us solve the triangle involving angle S and T.
Again applying the property that the sum of angles in a triangle must be equal to 180°
[tex]\begin{gathered} 48+57+S=180 \\ 105+S=180 \\ S=180-105 \\ S=75\degree \end{gathered}[/tex]As you can see, the angle S and T form a straight line angle.
Recall that a straight line angle is equal to 180°
[tex]\begin{gathered} S+T=180 \\ 75+T=180 \\ T=180-75 \\ T=105\degree \end{gathered}[/tex]Therefore, angle S = 75° and angle T = 105°
Now let us solve the remaining figure.
On the right side of the figure, apply the property that the sum of angles in a triangle must be equal to 180°
[tex]\begin{gathered} A+42+40=180 \\ A+82=180 \\ A=180-82 \\ A=98\degree \end{gathered}[/tex]As you can see, the angles A and B are opposite angles.
We know that opposite angles are equal.
[tex]\angle A=\angle B=98\degree[/tex]Now we know the angle B so let us apply the property that the sum of angles in a triangle must be equal to 180°
[tex]\begin{gathered} B+48+C=180 \\ 98+48+C=180 \\ 146+C=180 \\ C=180-146 \\ C=34\degree \end{gathered}[/tex]Therefore, angle A = 98° and angle B = 98° and angle C = 34°

a. Anna’s Share
b. Mark’s share.
c. The total sum
Answers
a)Sum of money share by Anna is $120000
b)Sum of money share by Mark is $72000
c) The total sum the three friends have is $ 240000
The ratio of the amount of money shared among three friends is 2: 3: 5.
Let's take the common factor to be x.
Sum of money Paul has = 2x
Sum of money Mark has = 3x
Sum of money Anna has = 5x
It is given that Paul receive $48000
So,
2x = 48000
x = 24000
a) Anna's share = 5x
= 5× 24000
= $120000
b) Mark's share = 3x
= 3 × 24000
= $72000
c) The total share = 2x + 3x + 5x
= 10x
= 10 × 24000
= $240000
Therefore the sum of money share by Anna is $120000, Mark is $72000 and the total sum of money is $240000.
