Question

solve this question (plzzzz)

Answer 1

angle cab =45°(alternate opposite angles r equal)

angle acb+angle dca=180°(linear pair)
angle acb+105=180
angle acb=180-105=75°

angle abc+angle acb+angle cab=180°(angle sum property of a triangle)
abc+75+45=180
abc+120=180
abc=180-120
=60°

hope it helps you
