Answer:

X=14

Step-by-step explanation:

If you measure them, they'll be very close to the same length.

Also, the triangles are very similar. Given this information, a simple way to solve it is:

12-4=8 so to find X subtract 4 from 18.

18-4=14 so X=14

I hope my brain did the correct math for you.

It probably didn't, but I tried.

How much heat is released when 12. 0 grams of helium gas condense at 2. 17 K? The latent heat of vaporization of helium is 21 J/
aleksandr82 [10.1K]

The amount of heat released when 12.0g of helium gas condense at 2.17 K is; -250 J

The latent heat of vapourization of a substance is the amount of heat required to effect a change of state of the substance from liquid to gaseous state.

However, since we are required to determine heat released when the helium gas condenses.

The heat of condensation per gram is; -21 J/g.

Therefore, for 12grams, the heat of condensation released is; 12 × -21 = -252 J.

Approximately, -250J.

frosja888 [35]

Answer:

Step-by-step Yes it is, assuming we decide to use the Pythagorean Theorem to find the hypotenuse (10) it'll be possible considering the formula is c²=√a²+b²

(c being the longest side of the triangle)

a= 6 and b= 8

c² =√6² + 8²

c² = √100 square root of 100 equals 10

c= 10p explanation:
