Hey in this type of questions there's no formula, you need to use your logic.
#Note that the full degree or a triangle is 180°
#The L in triangle is 90°
I see that you want to try to do it by yourself, i will give you the tips. to get the <BAD
#since <DAC is 90°, The ADB is 90° (180°-90°)
<BAD = 180° - 90° - 25° = 65°
Now, try to find <BCA yourself.
Tell me if you give up, i will tell you lol.
