12.) find the value of x and y. show all work.

The value of x = 90°

and the value of y = 43°

Step-by-step explanation:

Since we have given that

In ΔABC,

∠B=∠C=47°

As we know that "Sum of all three angles of a triangle is 180° ".

So, it becomes,

Similarly,

Now, in ΔABD,

Hence, the value of x = 90°

and the value of y = 43°
