Question

In the given figure triangle ABC and triangle ABD are right angled triangle. Calculate the value of BC and CD.
​

Answer 1

Answer:

Step-by-step explanation:

in triangle ABC

tan60 = AB / BC

root(3) = AB / BC { tan60 = root(3) }

BC = AB / root(3)

similarly in triangle ABD

tan30 = AB / BD

1 / root(3) = AB / BD { tan30 = 1 / root(3) }

BD = root(3). AB

CD = BD - BC

CD = root(3).AB - AB / root(3)

CD = AB ( root(3) - 1 / root(3))
