1.	408 is a straight line. Find x andalso determine the measure of each angle
Answer» Concept : Sum of angles in staright line is 180°.a) 6x + 4x = 180°10x = 180°x = 180°/10x = 18°So angles are 108°, 72° b) x/2 + x/3 = 180°5x/6 = 180°x = (180° × 6)/5x = 216°So angles are , 216/2 = 108° , 216°/3 = 72°

Concept : Sum of angles in staright line is 180°.a) 6x + 4x = 180°10x = 180°x = 180°/10x = 18°So angles are 108°, 72°

b) x/2 + x/3 = 180°5x/6 = 180°x = (180° × 6)/5x = 216°So angles are , 216/2 = 108° , 216°/3 = 72°
