1. if you have two angles, A and B, then since supplements add to 180, we have

A+B=180

if A's supplement is twice as large as A, then B=2A and we have

A+2A = 180
A = 60

3. where do you get stuck? Do you not know what it means to specify that two numbers add up to 180?

Do you knwo that "twice as large as A" means 2A?

do you not know that you can then substitute 2A for B in A+B?

do you not know that A+2A=3A?

if 3A=180, can you not deduce that A=60?
