Question

please find the answer to this and explain how it comes ​

Answer 1

Answer:

angle BDC=96°

angle ADB+BDC=180°. (linear pair)

so, 180-96= 84

Now, angle ABD = 3angleDAB

If angle DAB= X

then, angle ABD=3X

so, X+3X+ 84=180°. (sum of three angles of a triangle)

Now, 4X +84=180°

4X=180-84

4X=96

X=96/4

X=24
