I was wondering if you could show How you got the answer. And its not 6 I already tried TvT. Im looking for the surface area of

PIT_PIT [208]

Answer:

22, I think

Step-by-step explanation:

You count all the squares on all of the faces.

So you count the two on the top and double it for the bottom, so four

Then, on the sides you have three so you double that and get six

Next, you double the six squares on the other side and get twelve.

Lastly, you add them up!

4 + 6 + 12

Hope this helps!

Answer and explanation please

Answer:

x=17, y=12

Step-by-step explanation:

From the figure we know that,

Angle CDB = 4x-5

Angle BDE = 10y-3

Angle DEA= 97-2x

Though we are NOT given that line segments BD and AE are parallel, we may assume so by the construction of the triangle.

Hence, BD II AE and are cut by the transversal CE,

Hence,

Angle CDB = Angle CEA {Corresponding angles are equal}

$4x-5=97-2x\\4x+2x=97+5\\6x=102\\x=17\\\\So,\\Angle\ CDB\ = (4x-5) = (4*17-5) = (68-5) = 63$

As we observe that,

Angle CDB and Angle BDE form a linear pair, they are supplementary.

Hence,

Angle CDB + Angle BDE = 180

$Thus,\ 63+ Angle\ BDE=180\\Angle\ BDE\ = 180-63=117\\\\As\ BDE=(10y-3),\\117=10y-3\\117+3=10y\\120=10y\\y=12$
