Answer:
a
Step-by-step explanation:
Assuming that you mean "simplified form", we have to cancel every common divisor of both numerator and denumerator.
36 is factored as 
34 is factored as 
So, the two numbers only have a factor 2 in common, meaning that the simplified form of this fraction is

The fourth vertex would be at (2,5).
It has to be the same x value as (2,3) and the same y value as (-6,5)
Answer:
5:2
Step-by-step explanation:
When the length of sides are given, you can use law of cosine to find the angles

11^=8^2+5^2-2*8*5cosA
-80cosA=32
cosA=-0.4
A is about 114 degree
use the same method to find out B and C, you will get 42 and 25
