Answer:
similarly,on the graph in vertical line,x only takes value.thus, the equation for a vertical line is x=a,where is a value that x takes.
Look at the picture.
ΔABD and ΔBCD are similar, therefore:

Use Pythagorean theorem:
Idk but I think the answer you are looking for is D
Answer:
divided by 3 12/30 = 4/10 = 2/5
Step-by-step explanation:
Answer: 
Step-by-step explanation: 11/12 - 3/8
1. First, we will find a common denomenator. It needs to be the least common factor, or the answer will not be in its simplist form. Let's take a look at the multiples of 12 and 8.
12: 12, 24, 36, 48, 60, 72, 84, 96
8: 8, 16, 24, 32, 40, 48, 56, 64, 72
2. Next, we will choose the smallest common multiple. That would be 24.
3. Now, we will work this out.
11/12 = 22/24
3/8 = 9/24
4. Subtract.
22/24 - 9/24
= 13/24
= 
I found the denomenators by multiplying.
Hope this answer helped!
