Answer:
Step-by-step explanation:
PART A
The Pythagoras theorem is expressed as
Hypotenuse^2 = opposite side^2 + adjacent side^2
PART 2
The hypotenuse is the longest side of the triangle. Looking at the given triangle, the longest side is the side with the length of 7. Therefore, hypotenuse = 7
PART C
To determine x, we will apply the Pythagoras theorem as stated above. 
Opposite side = √14
Adjacent side = x
Therefore
7^2 = x^2 + (√14)^2
49 = x^2 + 14
x^2 = 49-14 = 35
Taking square root of both sides of the equation, it becomes
x = √35 
x = 5.92
 
        
             
        
        
        
Answer:
-5/12
Step-by-step explanation:
-1 times 1 is -1 so -1/3
2 times 2 is 4 so 4/5
 -1/3 divided by 4/5 
to make it easier we will write like this:
-1/3 times 5/4
-1 times 5=-5
3 times 4=12
so the final answer is  -5/12
