tiny-mole [99]3 years ago

Answer:

12

Step-by-step explanation:

the angles of a triangle all add up to 180

thus, we can combine every term given and set them equal to 180 and solve for x

9x + 72 = 180 \\ 180 - 72 = 108 \\ 108 \div 9 = 12

X= ?? geometry ??? And how ????
steposvetlana [31]

Using the equations for tangent and secant lines:

Let the unknown length of the line inside the circle = y

6^2 = 3 x (y+3)

Simplify:

36 = 3y+9

Subtract 9 from both sides:

27 =3y

Divide both sides by 3:

Y = 9

Now add to get x:

X = 9 + 3 = 12

X = 12

Help I'm stuck on this problem
ollegr [7]
Easy! 

All you have to do is make a number lower or higher according to the symbols and make it unique.

For example, on letter B, it says ____ - ____ = <1

So what you want to do is make it 0 - 0 = <1

use the picture to write each ratio as a simplified fraction (how are you going to find the length of the third side?) show your
Butoxors [25]

Answer:

<h3>See below</h3>

Step-by-step explanation:

to figure out the ratios we must figure out the length of <u>hypotenuse</u> first to do so we can consider <u>Pythagoras</u><u> theorem</u> given by

\displaystyle  {a}^{2}  +   {b}^{2}  =  {c}^{2}

\displaystyle \implies c =  \sqrt{ {a}^{2} +  {b}^{2}  }

substitute:

\displaystyle c =  \sqrt{ {12}^{2} +  {9}^{2}  }

simplify squares:

\displaystyle c =  \sqrt{ 225 }

simplify square root:

\displaystyle c = 15

now recall that,

  • \displaystyle  \sin( \theta)  =  \frac{opp}{hypo}
  • \displaystyle\cos( \theta)  =  \frac{adj}{hypo}
  • \displaystyle   \tan( \theta)  =  \frac{opp}{adj}

the ratios with respect to angle w given by

  • \displaystyle  \sin( W)  =  \frac{12}{15}  =  \frac{4}{5}
  • \displaystyle  \cos(W)  =  \frac{9}{15}  =  \frac{3}{5}
  • \displaystyle  \tan( W)  =  \frac{12}{9}  =  \frac{4}{3}

the following ratio with respect to angle X

  • \displaystyle  \sin(X)  =  \frac{9}{15}  =  \frac{3}{5}
  • \displaystyle  \cos(X)  =  \frac{12}{15}  =  \frac{4}{5}
  • \displaystyle  \tan( X)  =  \frac{9}{12}  =  \frac{3}{4}
