hope it helped you :)
There are 180 degrees in a triangle and if two of them are the same we can call them both a:
a + a + b = 180
2a + b = 180
Next, b is 12 degrees less than a so:
a - 12 = b
2a + a - 12 = 180
3a - 12 = 180
Add 12 to both sides
3a = 192
Find a:
a = 192 / 3
a = 64
This means angle 1 and angle 2 are equal to 64 degrees and angle 3 is 52 degrees
To check:
64 + 64 + 52 = 180 degrees
Answer: No, for example, 50/2=25, 25 isn't even
