To solve this problem, we need to apply trigonometric relationships. Let's break down the steps, using the given information:

Step 1: Analyze the triangle

We are given the following:

• $\angle A = 45^\circ$
• $\angle BDC = 54^\circ$
• $AB = 16$
• $DB = 14$
• Distance from $A$ to $D = y$
• Distance from $D$ to $C = x$
• Distance from $C$ to $B = h$

We are tasked with finding $x$ (the distance from $D$ to $C$) and $y$ (the distance from $A$ to $D$).

Step 2: Use the Law of Sines

To find $x$, we need to use the Law of Sines in triangle $BDC$. In any triangle, the Law of Sines states:

$\frac{a}{\sin A} = \frac{b}{\sin B} = \frac{c}{\sin C}$

In $\triangle BDC$, we have $\angle BDC = 54^\circ$, and we can calculate $\angle DBC$ using the fact that the sum of angles in a triangle is $180^\circ$:

$\angle DBC = 180^\circ - 45^\circ - 54^\circ = 81^\circ$

Step 3: Solve for $x$

Now apply the Law of Sines in triangle $BDC$ to solve for $x$:

$\frac{x}{\sin \angle DBC} = \frac{DB}{\sin \angle BDC}$

Substitute the known values:

$\frac{x}{\sin 81^\circ} = \frac{14}{\sin 54^\circ}$

Solve for $x$:

$x = \frac{14 \times \sin 81^\circ}{\sin 54^\circ}$

Step 4: Solve for $y$

Once $x$ is found, we can calculate $y$ using trigonometric relationships in triangle $ABD$, since $\triangle ABD$ involves $\angle A = 45^\circ$, and we can use either the Law of Cosines or another trigonometric relation to find $y$.

Let me compute the exact values for $x$ and $y$.The calculated distances are:

• $x$ (distance from $D$ to $C$): 17.1 units
• $y$ (distance from $A$ to $D$): 11.6 units
