Answer» As we know opposite angles of rhombus are equal Hence,<A = <C3x + 20 = x + 303x - x = 102x = 10x = 10/2 = 5 Thus,<A = 3*5 + 20 = 35°<C = 5 + 30 = 35° Now,<B = 180° - <A(sum of adjacent angles is 180)<B = 180° - 35° = 145° <B=145 your Questions Answer

Answer»

As we know opposite angles of rhombus are equal

Hence,<A = <C3x + 20 = x + 303x - x = 102x = 10x = 10/2 = 5

Thus,<A = 3*5 + 20 = 35°<C = 5 + 30 = 35°

Now,<B = 180° - <A(sum of adjacent angles is 180)<B = 180° - 35° = 145°

<B=145 your Questions Answer
