Since the interior angles of a triangle equal 180°, then 180-45=135.
Then you would use 135 to find the remaining two angles: b+3b=135.
4b=135.
Divide to find b. And the plug in whatever b is for the to figure out Angles B and C.
However, I believe the equation it's looking for is: 180=45+b+3b OR 45+4b=180
The answer is -12*20=-240 and add to 8. -12+20=8
1+1= 2
2+2= 4
3+3= 6
As you can tell from your answers it's is increasing by 2 each time.
HOPE THIS HELPS! ^_^
