Answer:
x=20
Explanation:
To find x use the fact that all triangle's angles sum to 180. This means that if you add all of the angles together, they will always equal 180 degrees. So, create an equation to represent this.
- The equation looks like this:
2x+65+75=180
- Then, combine the like terms
2x+140=180
- Next, subtract 140 from both sides
2x=40
- Finally, divide both sides by 2
x=20
This means that the missing angle is 40 degrees.
