1st number = x

2nd number = x+2

3rd number = x+4

x + x+2 +x+4 = 3x+6

3x+6 = 5(x+2)-18

3x+6 = 5x+10-18

3x+6 = 5x-8

3x+14 =5x

14 = 2x

x = 14/2 = 7

 1st number = 7

 2nd number = 7+2 = 9

3rd number = 7+4 = 11

What is the value of x?
Temka [501]

Answer:

x = 35°

Step-by-step explanation:

A triangle = 180°

The 95° is outside of the triangle so it must be smaller.

So say it is 85°

85 + 60 = 145

180 - 145 = 35
