Let the smaller number be x

So, greater number = 7 more than twice the smaller number

So, greater number = 7 + 2x

Sum of the two numbers = 43

So, 43 = greater number + smaller number

43 = 2x + 7 + x

43 = 3x + 7

Subtract 7 on both sides

43 - 7 = 3x + 7 - 7

36 = 3x

$\frac{36}{3}=\frac{3x}{3}$

12 = x

Smaller number = 12

Greater number = 2x + 7 = 2(12) + 7 = 31

31 and 12 are the two numbers,
2(x) + 7
x = 12
this might not be right but I think it is x

Answer:

85°

Step-by-step explanation:

Please follow along with these directions on the attached picture so that this makes sense. I have labeled the picture with the variables I used and the angles I figured out.

Let's start in the top left corner. Remember: triangles always have 180°, and straight lines always have 180°.

180-115 = 65

65+85+x = 180, so x = 30

30+90+y = 180, so y = 60

180-155 = 25

25+60+z = 180, so z = 95

180-95 = 85°
