Answer:
The length of he hypotenuse of the triangle is x = 65.
Step-by-step explanation:
Here, the base of the right triangle = 56
The perpendicular = 33
The hypotenuse of the triangle = x
Now, by PYTHAGORAS THEOREM: In a right angled triangle

or, here

or, 
Hence, the length of he hypotenuse of the triangle is 65.
1- y= x/2 + 2
2- y= 3x +1
3- y= x/2 - 2
4- y= 3x - 1
ABCD is a square . if the coordinates of three of its vertices are A(-1,2a), B(a,2a), C(a,0), find the coordinates of D. BC is obviously 2a (it's a vertical line) then AB must be 2a (notice AB is horizontal) so BC = AC because it is a square 2a = a+1 a=1
