Answer: Therefore it must be the first one, 40
Step-by-step explanation: Vertical angles are always congruent, which means that they are equal. x = 40
4:4 and 5:5 are <span> two ratios that are equivalent to 1:1</span>
Bla bla bla your answer is x=4.95

Answer: 12.5 (choice C)</h3>
=================================================
We apply the pythagorean theorem to find this answer.
a = 11 and b = 6 are the given legs
c = unknown hypotenuse
So,
a^2+b^2 = c^2
c = sqrt( a^2+b^2 )
c = sqrt( 11^2 + 6^2 )
c = sqrt( 121 + 36 )
c = sqrt( 157 )
c = 12.52996 approximately
c = 12.5
Side note: once you replace 'a' and b with 11 and 6, you can compute everything with a calculator in one single step more or less. The steps above are shown if you wanted to find the exact value sqrt(157).
Answer:
hey, hope this helps :)
Step-by-step explanation:
1. Matter changes state because of physical pressure and temperature; properties do not change.
heating gives molecules energy that causes them to vibrate faster, breaking their bonds and melting.
3. Heat energy that helps break the molecular bonds of a solid is heat of fusion
4. The temperature at which a liquid turns into a gas is the boiling point.
5. sublimation is when a solid turns straight into a gas.
