Algebra: find the value of each variable

Hey, I'm not too quite sure about my answers, but I figured I'd give it a shot.

Let me show you what I did to get my answers.

1. Those little ticks on the triangles means that they're equal. A triangle has a sum of 180 so I took:

2x+2x+40=180

4x+40=180

4x=140

x=35

2. The curves on the sides means that they're also equal so I did:

2x+6=3x-6

2x=3x-12

-x=-12

x=12

4. This is similar to #1. Keep in mind that a right angle has a degree of 90.

5x+5x+90=180

10x+90=180

10x=90

x=9

5. Repeat.

6x+6+6x+6+2x=180

14x+12=180

14x=168

x=12

0.84 dang lotta people are looking for this lol or if you round up its 1 but the overall answer to that is 0.84
