All I want to know is the formula and I will do the rest...pls someone help me with the formula...

Step-by-step explanation:

dude do ur homework urself love you daddy :)

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.
