What is BD? Plzzzsss Helppp

Answers

Answer:

Step-by-step explanation:

since the two angles are the same we can set up a relationship between the two triangles and set them equal to each other and solve for X  :) , as follows

SOH   sin = Opp / Hyp

triangle 1  )   sin(Ф) = x / 12

triangle 2 )    sin(Ф) = x + 5 / 27

since sin(Ф) is the same for each triangle.. set those other sides equal to each other

x/12 = x+5 /27

now solve for x using your mad algebra skilz  :P

27 / 12 = x + 5 / x

2 3/12  = x/x  + 5/x

2 1/4 = 1 + 5/x

1 1/4 = 5/x

x = 5 / 1 1/4

x = 4   nice  :)

So BD is then

4 + 4+5

so BD = 13  

tell your professor / teacher that you figured it out all on your own  :D

( yes.. that was tricky to figure out )

In a right triangle the hypotenuse which is 16+9 =25 has to be the largest side.  Since x is not the hyportenuse it has to be lower which only leaves one answer : 15

Answer:

Step-by-step explanation:

these are tough to solve  , don't feel bad.   soo part of the trick is that the two side set  up similar triangles, then  

16 / y  = y /9     ( the two triangles

16* 9 = [tex]y^{2}[/tex]

144 = [tex]y^{2}[/tex]

12 = y

y is the length between the two triangles , so since we now know that part, we can solve the triangles.

lets use tan to solve one of the angles of the smaller triangle

TOA  to remember how tan fits on a triangle

Tan = Opp / Adj

Tan(Ф) = 9/12

Ф = arcTan(9/12)

Ф = 36.869897

knowing that we can solve for x

use CAH   cos = Adj / Hyp

Cos(36.869897) = 12 /  Hyp

Hyp = 12/ Cos(36.869897)

Hyp = 15   :)  that seems reallly good ..  :P

x = 15   there you go

Answer:

  not similar

Step-by-step explanation:

For the triangles to be similar, at least two angles must match. Here, there is an 81° angle in both triangles. This means the sum of the remaining two angles must be ...

  180° -81° = 99°

If the missing angle in either triangle matched the other given angle in the opposite triangle, the sum of those would be 60° + 40° = 100°, not 99°. This triangle pair does not have two matching angles, so the triangles are not similar.

ABC angles: 60°, 81°, 39°

FED angles: 59°, 81°, 40°
