Answer: The value of x = 7 and the value of y = 7√2.
Step-by-step explanation:
Since we have given that
Let ABC is a right angled triangle , right angle at B.
AB = 7
BC = x
AC = y
∠ACB = 45°
We need to find the value of x and y:
As we know the "Trigonometric ratio":
Similarly,
Hence, the value of x = 7 and the value of y = 7√2.

<h3>What is the transformation rule?</h3>In coordinate planes, the rule of transformation involves interchanging the x and y values on the plane such that:
where;
- k = scale factor
From the given information:
- The scale factor = 2
- the origin as a center of dilation for image vertices = (0, 0)
Now, using the coordinate vertices:
- A = (-1, -1)
- D = (2, -1)
The corresponding coordinate of the image vertices is as follows:
A(-1,-1) → A'(2 × (-1), 2 × (-1))
A' = (-2,-2)
D(2,-1) → A'(2 × (2), 2 × (-1))
D' = (4,-2)
