Answer» Let first angle = 5xand second angle = 4x we know, sum of two adjacent angles =180° so,5x + 4x = 180°9x = 180°x = 20° so, first angle = 5x = 5×20=100°second angle = 4x =4×20= 80°

Answer»

Let first angle = 5xand second angle = 4x

we know, sum of two adjacent angles =180°

so,5x + 4x = 180°9x = 180°x = 20°

so, first angle = 5x = 5×20=100°second angle = 4x =4×20= 80°
