Answer:
x = 34
Step-by-step explanation:
The 3 given angles form a straight angle and sum to 180°, hence
x + 12 + 100 + x = 180
2x + 112 = 180 ( subtract 112 from both sides )
2x = 68 ( divide both sides by 2 )
x = 34
Well the other guy had 20% but then he got five dollars now it is 25% so what is 25% +25%

The height of the envelope is 10. This is because you divide the area by 3. So, the missing side is 10 inches.
Answer:
22.5
Step-by-step explanation:
All of the angles inside the triangle equals 180. Therefore, the equation is x+2x+5x=180. Then, you solve for x. The final equation should look like 8x=180 And that is how we get.22.5
