Question

In the figure, the point B lies on AC such that AB = 8 m, BD = 9 m, ABD = 125° and BCD=
Find
(i) the length of CD
(ii) the length of AD​

Answer 1

Step-by-step explanation:

Given, AB=8cm;BC=4cm

Perpendicular distance between AB and BC is DL=3cm

The area of the parallelogram =base×height

=AB×DL

=8×3=24cm

2

Area of the parallelogram =base×height

=AD×BM

24=4×height

Height=6cm

So the perpendicular distance between AD and BC is 6cm
