hey!

i) we know that sum of interior angles = exterior angle of triangle

x+56°=123°

x=123-56

x=67°

ii)45°+(3x+16)+68= 180° (Angle sum prop.)

3x+129°=180

3x=180-129

3x=51°

x=51/3

x=17°

iii) Same as question 2 with the help of ANGLE SUM PROPERTY

iv) same (A.S.P) we will take angle x as x and the use the property
