What does "its supplement is twice as large" mean?
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
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?
The phrase "its supplement is twice as large" is used to compare the size of one thing (denoted as "it") and its supplement. In this context, a supplement refers to something that completes or enhances the original thing.
To understand this phrase, you need to know the meaning of "twice as large." When we say something is "twice" as large, it means that its size is multiplied by 2. For example, if the original thing is 5 units in size, its supplement would be 5 x 2 = 10 units in size, which is twice as large.
In summary, "its supplement is twice as large" means that the size of the supplement is double the size of the original thing being referred to.
