Answer:

$\frac{8}{14} = \frac{14}{x+2}$ (since they're similar, set them up as a proportion to find x)

14*14 = 8(x+2) (cross multiply, solve the left side, and distribute the right side)

196 = 8x +16 (subtract 16 from both sides)

180 = 8x (divide both sides by 8)

x= 22.5 (is your answer, or C)

Help i’m taking a test and i’m being timed

Nuetrik [128]

Answer:

5.4

Step-by-step explanation:

Using the pythagorean theorem (a^2 + b^2 = c^2), we can do 2^2 plus 5^2, which is 4 + 25, which simplifies to 29. Now we have 29 = c^2

In order to find c (the hypotenuse), we need to take the square root of both sides to find c. Thus, c = sqrt 29 or 5.385...

Hope this helps!

Which of the listed values are equal to the sine of C A.)b/a B.)c/a C.)c/b D.)cos B E.)5.Cos C F.)cos (90°-C) G.)cos(90°-B)

kherson [118]

Answer:

Sine of C=?

Among the given options which is the correct one.

Step-by-step explanation:

Consider a right-angle triangle ABC.

$angle B=90^{0}$

In a right angle triangle, one angle $90^{o}$ .

The sum of all the angles is $180^{o}$ .

$angle A +angle B+angleC=180^{0}angleA+90^{0} +angle C=180^{0}\\angleA+angleC=180^{0} -90^{0} \\angleA+angleC=90^{0} \\angleA=90^{0} -angle C$

Consider the trigonometric ratios and use the traingle ABC.

$SinC=\frac{AB}{AC}$

$CosA=\frac{AB}{AC}$

$angleA=angle(90-C)\\Hence,\\SinC=Cos(90-C)$

Answer:

OptionF). $Sine of C=Cos(90^{0} -C)$

Hurry hurry hurry hurry 50 points help plz help...it would be better if you have a picture..plz use steps

Ymorist [56]

Our goal here is to create a copy of line segment PQ, through various steps. Let's start with drawing line segment PQ, respectively point R a fixed distance away from the segment.

It would be wise to use a compass in this case, and a ruler for certain.

So we have this segment PQ, and point R a " fixed distance " away from PQ.

( 1. Extend a compass to match with the length of PQ,

( 2. Move this compass ( without changing it's length ) so that one endpoint matches with point R

( 3. Now draw an arc with this compass, where this line will be

( 4. Take your ruler and draw a straight line from this point R to your arc. It would be wise to draw this line to the middle of the arc you created.

If you like, take a look at the attachment below to see what it should look like.

I have done these questions before, so I can assure you that this experiment is proved correctly!
