Answer:
180-degree angle
This is not a 90-degree angle because if it were to be, then it would be AB, which is not what we are going for, which leaves BC as 180 degrees (if you see it on a protractor)
Answer: the answer is 661.55
Step-by-step explanation:
interest formula: F = Pe^(rt)
Answer: x= 1, 
Step-by-step explanation:
The quadratic equation is

and

So we just need to sub in the proper numbers from the equation given, in this case, it would result in

and

Once we get this we can either manually simplify or use a calculator, using a calculator would result in the answers
x= 1, 
1. 16/9 simplified
2. 99/6= 33/2
3.4/9 simplified
4. 6/4= 3/2
5. 6/13 simplified
