All this is, is plugging in numbers. Then taking the square root of it. The first one would be the square root of 6 squared - 4(5)(-3). That would simplify to the square root of 36+60. Then add the numbers to get the square root of 96. The square root of 96 is about 9.798. I hope that helped. If you still need help with the second one or with the rest of the formula (if there is one) just ask!
Answer:
Angle 2
Step-by-step explanation:
They are immediately across from each other and measure the same degrees.
Hey there! :D
Subtract 20% by 10%, because it is asking how much less than the original price was by what percent.
20%-10%= 10%
The ticket was 10% less than the original ticket.
I hope this helps!

A compass and straightedge are supposed to be part of the required equipment for your class. You are expected to use them here. Your assignment paper should be complete with pencil marks and holes from the compass point. Nobody can do it for you on-line.
Here is a picture of the first one worked. The remaining ones are just like it. The whole assignment should take about 3 minutes, tops.
