You can use the measure of 112 on the similar shape to find b, as they are same side exterior angles. From there, you can find both a and c, because a/b and b/c are supplementary angles.
a = 68 degrees
c = 68 degrees
0.7(5x+15)=2.9 -(x+3)
3.5x+10.5=2.9-x-3
3.5x+10.5= -0.1- x
4.5x= -10.6
x= -2.3555...
Check:
0.7(5(-2.3555...) +15) = 2.9 -(x+3)
2.2555... = 2.2555...
the factors of the term
are 
Step-by-step explanation:
We need to find factors of the term: 
For finding factors:
We need to break the middle term such that their product is equal to product of first and last term and their sum is equal to middle term
Breaking the middle term and finding factors:




So, the factors of the term
are

No they're not proportional, and it's four*.
4/2 = 2
20/6 = 3.333333333334 or 3 1/3
