Hello, i solvee it but the book doesn't give an answer.

In triangle ABC (see Figure 1.4), BCA = 90◦, and D is the foot of

the perpendicular line segment from C to segment AB. Given that |AB| = x and

A = θ, express all the lengths of the segments in Figure 1.4 in terms of x and θ.

The way i started it:

I found that theta=45 degrees as well as all angles are =45 Both triangles are isosceles 45-45-90 triangle. X=sqrt(2)

P.S exercise of Algebra & Trigonometry as well as some geometry. But this problem i didnt use trig so i think my solution is false.
