Question

in a trapezium abcd ab is parallel dc and angle c=60 degrees angle d=45 degrees if ab =6cm and bc=4cm find the height of trapezium and length of dc​

Answer 1

Answer:

so chico

Step-by-step explanation:

Draw a line parallel to AD as given in the below figure. That implies DE=6cm and EC=5cm.

Now we get a triangle EBC with sides 3,4 and 5 cms.

Area= 0.5*b*h = Sq.root( s*(s-a)(s-b)(s-c))

s= (3+4+5)/2 = 6

0.5*5*x = Sq.root (6*(6–3)(6–4)(6–5))

5/2*x = 6

x= 12/5 = 2.4cms
