Answer: 105

Step-by-step explanation:

Angle A, B, and C all add up to 180 degrees. So you combine the equations and get “6x+30=180” so x=25 and then you plug 25 for x into the equation for angle B and you get “75+30” which equals “105”.

ankoles [38]
10*3=30
30*3=90
90*3=270
270*3=810

or

10*3^1=30
10*3^2=90
10*3^3=270
10*3^4=810

the next two terms of this sequence are 270 and 810.

The density of lead is 11.4g/cm^3 at 25 degrees C. Calculate the volume occupied by 25.0g of lead
ElenaW [278]

Answer:

2.193 cm³

Step-by-step explanation:

density is mass divided by volume:

density =  \frac{mass}{volume}

you can manipulate the formula by multiplying with volume:

density \times volume = mass

then dividing by density:

volume =  \frac{mass}{density}

in this case:

volume =  \frac{25g}{11.4 \frac{g}{cm}  }  = 2.193 { \: cm}^{3}

When finding out if 2 triangles are congruent, is it possible to only use a side and angle if those are the only 2 provided? Hel
PIT_PIT [208]
Short answer: No and yes. 
Yes First.
If the lower right point (looks like an C perhaps or an F) and the middle point and the upper left point lie on the same line and if D the middle point and the upper right point lie n the the same line, then yes. You have angle side angle. The lower right angle is given as equal to the upper left angle. The angles at C are vertically opposite angles and they are equal and you have been given 2 enclosed sides that are equal.

No
If the points I've described are not on the same line, then the triangles are not congruent. If I can, I'll edit this a second time. 

Please Note:
You have done something that looks a bit illegal to me. I wouldn't just trade pictures. It only costs you another 5 points to issue another question. I do think, however, that it is very clever. In answering about 1700 questions, I've never seen this done. That's commendable.
