Answer:
 and
 and 
Step-by-step explanation:
Given:
 .......................... equation i
 .......................... equation i
 ........................ equation ii
 ........................ equation ii
since y is equals to the two functions , we can equate the two values of y . That is , equate equation i and ii , we have 

Add  to both sides , we have
 to both sides , we have


subtract 3 from both sides , we have 

divide both sides by 4 , then

substitute  into equation i to get the value of y , that is
 into equation i to get the value of y , that is



Therefore :

Answer:
   x = y = 12
Step-by-step explanation:
A right triangle with a 45° angle is an isosceles right triangle. That means the legs are both the same length. The side ratios of such a triangle are ...
   1 : 1 : √2
Multiplying these ratios by 12 gives ...
   12 : 12 : 12√2 = x : y : 12√2
The side lengths x and y are both 12 units.
