Answer:
13, 22
Step-by-step explanation:
Let s represent the smaller. The sum of the numbers is ...
s + (s+9) = 35
2s = 26 . . . . . . subtract 9
s = 13
s+9 = 22
The two numbers are 13 and 22.

<em>Additional comment</em>
As you can see, the smaller number is half the difference of the sum and difference: s = (35-9)/2. This is the generic solution to a "sum and difference" problem.
Answer:
3=95 vertically opposite angle
2+95=129 exterior angle is equal to the sum of two opposite interior angle of a triangle
2=129-95=34 answe
4+3+47=180 sum of interior angles of a triangle is 180
4=180-47-95=38 answer
Step-by-step explanation:
