The two triangles are similar and equal therefore; It means the corresponding sides are equal and the corresponding angles are equal. Hence;
 ZX=EF, thus,ZX = 1.3 in. 
EG = XY, thus, EG = 3.0 in.
m∠ X = m∠E, thus m ∠X = 48°
m∠ G = m∠Y, and angles in a triangle add up to 180 thus;
  m ∠ G=180- (107 +48) = 25°

The triangles are given to be congruent which means that their corresponding angles and sides will have to have similar measures and similar lengths. 

a. ZX = __ in
 The length of ZX is equal to the length of FE. Hence, the length should be equal to <em>1.3 in</em>. 

b. EG = __ in
 The length of EG is equal to the length of XY. From the figure, the answer should be <em>3.0 in</em>.

c. m∠X = __°
 The measure of angle x should be equal to the measure of angle E. This is given to be equal to <em>48°</em>.

d. m∠G
  The measure of angle F is equal to the measure of angle Z. Th measure of angle F should then be equal to 107°. In the triangle in the right, the measure of angle E is 48°, the measure of angle F is 107°, subtracting the sum of these angles from 180°, we are then left with measure of angle G which is equal to <em>25°</em>.

A missing fraction on a number line is located exacly halfway between 3/6 and 5/6. What is the missing fraction?
kap26 [50]
The missing number would be 4/6, or 2/3.

The missing number can be found by finding the absolute distance in between the numbers, dividing it and then adding it to the smaller number.

(5/6-3/6)/2=(2/6)/2=1/6
3/6+1/6=4/6 or 2/3

The sum of 6 consecutive integers is 270. What is the second number in the sequence?
Rina8888 [55]
N+(n+1)+(n+2)+(n+3)+(n+4)+(n+5)=270
We use these terms to represent the first six consecutive integers in the sequence
Now we group like terms:
6n+15=270
Minus 15 from both sides of the equation
6n=255
n=42.5 which is not an integer
Is this a joke question?
Besides that, the 2nd number will be 43.5

30 POINTS,NEED HELP ASAP !!!
zaharov [31]

Answer: OPTION A.

Step-by-step explanation:

You can observe that in the figure CDEF the vertices are:

C(-2,-1),\ D(-2,0),\ E(2,2)\ and\ F(2,1)

And in the figure C'D'E'F'  the vertices are:

C'(-8,-4),\ D'(-8,0),\ E'(8,8)\ and\ F'(8,4)

For this case, you can divide any coordinate of any vertex of the figure C'D'E'F' by any coordinate of any vertex of the figure CDEF:

For C'(-8,-4) and C(-2,-1):

\frac{-8}{-2}=4\\\\\frac{-4}{-1}=4

Let's choose another vertex. For E'(8,8) and E(2,2):

\frac{8}{2}=4\\\\\frac{8}{2}=4

You can observe that the coordinates of C' are obtained by multiplying each coordinate of C by 4 and the the coordinates of E' are also obtained by multiplying each coordinate of E by 4.

Therefore, the rule that yields the dilation of the figure CDEF centered at the origin is:

(x, y)→(4x, 4y)
