It is given in the question that:
QS bisects angle mmBut angle So angle So :
Angle Angle Note that angles on a straight line add up to 180 degrees so ;
angle But from the question we have :
Angle Then 8x +10 =42
8x = 42-10
8x = 32
x = 32/8 = 4 degrees
Thus 84 + So Now you have values of all angles as:
and
Value of x is = 4 degrees
