Answer:
x = 53°
(x+2)° = 55°
Step-by-step explanation:
Well we know that all the three angles added up together equals 180, so we can set the value of all the angles added up together as 180:
[tex]x+(x+2)+72= 180[/tex]
Now lets add what we can together:
[tex]2x+74=180[/tex]
Since we want to get x by itself to find its value, lets move 74 onto the other side and isolate the x:
[tex]2x=106[/tex]
[tex]x = 53[/tex]
And now we have the value of x, but let's plug them in and see if they still all equal to 180:
[tex](53+2)+53+72=180[/tex]
[tex]180 = 180[/tex]
