if X be the area of a right angled triangle ABC,in which angle ABC=90 and BC = b
Answers
AB = x = 70.980
BC = x-30 = 40.980
Given
To find the value of x.
Let x cm be the area of the right angled triangle AB.
∠ABC = 90° ; ∠ACB = 60° ; ∠ADB = 45° ; CD = 30 cm
In right angle ΔABD,
= tan 45°
( AB = x ; tan 45° = 1 )
BD = x cm.
Where, BC = BD - CD
= x - 30
BC = x - 30
In right angle ΔABC,
= tan 60°
=
Conjugating the value, it gives
×
AB = x = 70.980
BC = x-30 = 70.980 - 30 = 40.980
