Question

14 The figure shows a rhombus and an equilateral triangle joined together.
(a) C
(b) ZABD
(c) E
(d) A​

Answer 1

Answer:

(a)angle c= 60 degree (because a equilateral triangle has all angles equal)

(b)angle ABD= 120 degree(because angle b in equilateral triangle and angle b in rhombus are adjacent angles or linear pair.so 180-60=120)

(c)Angle e = 120 degree (because angle b and angle e are opposite angles,are equal in rhombus)

(d)angle a= 6o degree(because angle b and angle a are adjacent angles,the sum of adjacent angles is 180 degree)
