Answer. Temperature affects phase change by slowing down the movement in between the atoms, thus causing a change in kinetic energy, which in turn causes the atoms to undergo forms of combining or a type of disepersion.
Answer:
y = 4
Step-by-step explanation:
because 5 x 4 = 20 and 20 × 4 = 80 and so on y is equal to four
Answer:
Part 1) ![m\angle AFE=55^o](https://tex.z-dn.net/?f=m%5Cangle%20AFE%3D55%5Eo)
Part 2) ![m\angle EFB=125^o](https://tex.z-dn.net/?f=m%5Cangle%20EFB%3D125%5Eo)
Step-by-step explanation:
Part 1) what is the measure of angle AFE
we know that
The measure of the interior angle is the semisum of the arches that comprise it and its opposite.
<u>Note:</u> In this problem the correct measure of arc EA is 40 degrees (see the picture)
so
![m\angle AFE=\frac{1}{2}(arc\ EA+arc\ DB)](https://tex.z-dn.net/?f=m%5Cangle%20AFE%3D%5Cfrac%7B1%7D%7B2%7D%28arc%5C%20EA%2Barc%5C%20DB%29)
substitute the given values
![m\angle AFE=\frac{1}{2}(40^o+70^o)=55^o](https://tex.z-dn.net/?f=m%5Cangle%20AFE%3D%5Cfrac%7B1%7D%7B2%7D%2840%5Eo%2B70%5Eo%29%3D55%5Eo)
Part 2) what is the measure of angle EFB?
we know that
---> by supplementary angles (form a linear pair)
so
substitute the given value
![55^o+m\angle EFB=180^o](https://tex.z-dn.net/?f=55%5Eo%2Bm%5Cangle%20EFB%3D180%5Eo)
![m\angle EFB=180^o-55^o=125^o](https://tex.z-dn.net/?f=m%5Cangle%20EFB%3D180%5Eo-55%5Eo%3D125%5Eo)
