For this triangle in particular, we can use the special rules of a 30-60-90 triangle
This says:
The opposite side of 30° is: x
The opposite side of 60° is: x * sqrt(3)
The opposite side of the 90° is: 2x
We have our side length for 90° so we just have to work backwards
To find our 30° side length we must divide by 2
8/2 = 4
Which means your y = 4
Now that we have our 30° side length we can just multiple it by sqrt(3)
That means your x = 4 sqrt(3)
The answer would be 8! This is because there were already five and then Jason got in, so six, and then two friends got in as well, so six plus two is eight!
Answer:
18 pages per hour.
If you do 36 (the pages/amount) divided by 2 (The time), you get 18.
To double check, when you do 90 (The pages/amount) divided by 5 ( The time), then you get 18 again.
Therefore the answer is 18 pages per hour.

Step-by-step explanation:
(5x+18) - (3x+12)
5x+18=3x+12
5x-3x=2x
18-12=6
2x+6
