A somatic mutation is change in the DNA sequence of a somatic cell of a multicellular organism with dedicated reproductive cells; that is, any mutation that occurs in a cell other than a gamete, germ cell, or gametocyteA somatic mutation is change in the DNA sequence of a somatic cell of a multicellular organism with dedicated reproductive cells; that is, any mutation that occurs in a cell other than a gamete, germ cell, or gametocyte
This is a very simple question
As I don't know what do we have to prove so I will solve this completely
>given
Angle cab = 50°
Angle acb = 30°
Angle bdc = 55°
To find
> y
=> cab + abc + acb = 180° (angle sum property)
= 50° + abc + 30° = 180°
= 80° + abc = 180°
=Abc = 180° - 80°
____________Abc = 100°___________
Now to find Y
Angle abc + angle dbc = 180° (linear pair)
= 100° + dbc = 180°
= dbc = 180° - 100°
= dbc = 80°
Therefore,
Dbc = y
So y = 100°
This will definitely help you
