Answer:

In triangle DEF:

Given:  m\angle D = 20^{\circ} ,  m\angle E= 120^{\circ} and  m\angle F = 40^{\circ}

To list the sides of a triangle in order from shortest to longest.

In the Figure as shown below :

If one of the angle of a triangle is larger than, then the sides opposite the larger angle is longer than the side opposite to the shorter

m\angle D < m\angle F < \angle E

\text{EF} < \text{DE}

Therefore, the list of the sides of a triangle DEF in order from shortest to longest is, \text{EF} < \text{DE}

Answer:

<h2>From shortest to longest:</h2><h2>EF, DE and DF.</h2>

Step-by-step explanation:

We know that m∠D = 20, m∠E = 120, and m∠F = 40.

Knowing this measures we can order the sides from shortest to longest, because angles are the opening between to sides, this means if the angle is wide, its opposite side (which is in front of the angle) is wide too, if the angle is narrow, its opposite side will be narrow.

So, in this case, the opposite side of ∠E will be the longest, because this is the largest angle. The opposite side of m∠F will be the second longest, and the opposite side of ∠D will be the smallest. From shortest to longest the order is: EF, DE and DF.

The image attached show this result.

Let x represent the number of hours you read a book and y the total number of pages you have read,You already read 70 pages and
nadezda [96]
X=number of hours you read
y=number of pages

y=30x+70
number of pages after 3 hours:
y=30(3)+70
y=90+70
y=160

therefore, 160 pages after 3 hours

Answer:

Step-by-step explanation:

a-number of advance  tickets

s-number of same day tickets

a*40+s*25=2400

a      +s      =75

I solve  with the substitution method

s=75-a

40a+25*(75-a)=2400

40a+1875-25a=2400

15a=2400-1875

15a=525

a=525/15

a=35

so  s=75-35

s=40

Translate Δ A B C 6 units horizontally. How are the values in the ordered pairs affected by the translation?
snow_tiger [21]

Answer:

The x-coordinates are translated 6 units to the left or right while the y-coordinates are not affected.

Step-by-step explanation:

The given triangle has vertices at A(-4,1), B(-2,1) and C(-2,4)

The transformation rule for a horizontal translation by k units is

(x,y)\to (x\pm k,y)

In this case we have k=6

A(-4,1)\to A'(-4\pm6,1)

B(-2,1)\to B'(-2\pm6,1)

C(-2,4)\to C'(-2\pm6,4)

Therefore the x-coordinates are translated 6 units to the left or right while the y-coordinates are not affected.
