Answer:
x=6
Step-by-step explanation:
4(3+x)=36
12+4x=36
4x=36-12
4x=24
x=6
Proof: 4(3+x)=36
4(3+6)=36
12+24=36
36=36

The sum of angles of a pentagon is 540°, so x must be chosen to make that so.
85 + 110 + x + 120 + 120 = 540
540 -435 = x = 105
_____
The formula usually used to find the degree measure of the internal angles of an n-sided polygon is (n -2)·180°. For n=5, this is 3·180° = 540°.
2*10000 is 20000.
Start your expanded form with 20000. Add 7000, add 400, add 9, add 0.3 and add 0.008:
