Question

7. In the trapezium ABCD, AB || DC and
ZC = 60°, ZD=45°. If AB=6 cm and BC =4 cm,
find
(i) the height of the trapezium
(ii) length of DC​

Answer 1

Answer:

Given, ABCD is a trapezium and whose parallel sides in the figure are AB and DC.

Since, AB || CD and BC is transversal, then sum of two cointerior angles is 180°.

angle b + angle c = 180

angle c = 180 - angle b

180-45=135 degree

angle c = 135 degree

angle a + angle d = 180

angle d=180-45

angle d=135 degree
