45+2a=180. You should always try to write down an equation for problems like these. Subtract the 45 to both sides of the equal sign. This gets you 2a=135. Divide the 2 on both sides and you get a=67.5 degrees. I hope that i helped, enjoy
Answer:
Yes, -x - 3y = -1 is the same as y = -1/3x - 1/3
Step-by-step explanation:
-x - 3y = -1
Add x to both sides which gives you
-3y = x-1
Divide both sides by -3 which gives you
y = -1/3x-1/3
Reminder whatever you do to one side you have to do to the other side!
Hope this helps!
