Answers

Answer 1

Answer:

c (6)

Step-by-step explanation:

by the corresponding angles postulate, the angle above 20x-5 will be 65°.

20x - 5 + 65 = 180 they are supplementary angles (angles that add up to 180°)

20x + 60 = 180

20x = 120

x = 6

Answer:

y = 8; x = 6 [tex]\frac{7}{8}[/tex] ; n = 1 [tex]\frac{2}{23}[/tex] ; p = 55

Step-by-step explanation:

First proportion

// How to solve it

// firstly, multiply both sides by y, so that y would be in numerator

[tex]\frac{16}{16} * y[/tex] = [tex]\frac{8}{y} * y[/tex]

// now we get

[tex]\frac{16y}{16}[/tex] = 8

// secondly, divide both sides by [tex]\frac{16}{16}[/tex], so that we'd have y on one side and the expression on the other side

y = [tex]\frac{16}{16}*8[/tex]

// since [tex]\frac{16}{16}[/tex] = 1

y = 8

Second proportion

// divide both sides by 22, so that there'd be unknown variable x on one side and the expression on the other side

x = [tex]\frac{10*22}{(y*4)}[/tex]

Is this y from the first proportion?

If so, then x = [tex]\frac{10*22}{(8*4)}[/tex] = [tex]\frac{220}{32}[/tex] = [tex]\frac{55}{8}[/tex] = 6 [tex]\frac{7}{8}[/tex]

Third proportion

// divide both sides by 5

n = [tex]\frac{5}{23} * 5[/tex] = [tex]\frac{25}{23}[/tex] = 1 [tex]\frac{2}{23}[/tex]

Fourth proportion

// divide both sides by 10

p = [tex]\frac{22}{4} *10[/tex] = 55

What is the value of f if 9f+11=3f+23

Answers

Answer:

f=2

Step-by-step explanation:

F = 2

9f+11
If f is two, 9f = 18.
11+18= 29

3f +23
If F is two, then 3f = 6.
6+23=29.

Well, look there- both answers are equal so F equals 2

F=2

Answers

Answer: x= 10

Step-by-step explanation:

Same side exterior angles sum to 180.

Using this axiom we can say that

142+ (3x+8) = 180

Add like terms on the left side

150+ 3x = 180

Subtract 150 from both sides

3x = 30

Divide both sides by 3

X= 10

If 72 = 12x, what does x equal?

Answers

Answer:

x=6

Step-by-step explanation:

So, x is our unknown variable. An so you have to ask yourself, what times 12= 72? The answer would be 6, because 12x6=72

The proper way to do it, would be to divide 12/12 so you isolate the variable, and what you do to one side, you do to the other, so divide 72 by 12 and you get 6! Hope this helps!

In addition to the information given below in the drawing, which statement is sufficient to prove triangle STW similar to triangle XYZ?

Answers

D

XZ : YZ = 5:8

3 * XY = 27 (9*3 = 27)

3*XZ : 3*YZ = 3*5 : 3*8

SW : TW = 15 : 24

SW = 15 and TW = 24

The additional information which needed to prove triangle STW similar to triangle XYZ are SW = 15 and TW = 24

What are similar triangles?

Two triangles are similar if they have the same ratio of corresponding sides and equal pair of corresponding angles. If two or more figures have the same shape, but their sizes are different, then such objects are called similar figures.

Given that, two triangles STW and XYZ, ST = 27, XY = 9, YZ = 8 and XZ = 5

We need to select a statement which will complete the proof of Δ STW ~ Δ XYZ

We know that, Similar triangles have the same corresponding angle measures and proportional side lengths.

If we consider Δ STW ~ Δ XYZ,then we get,

ST / XY = TW / YZ = SW / XZ = 3

Therefore,

SW / XZ = 3

SW / 5 = 3

SW = 15

Also,

TW / YZ = 3

TW / 8 = 3

TW = 24

Hence, the additional information which needed to prove triangle STW similar to triangle XYZ are SW = 15 and TW = 24
