In ∆ABC ,AB =6√3 cm, AC =12 cm ,BC = 6 cm. Find the measure of ∠A *
Answers
Solution:-
In ABC, AB = 6v3 cm, AC = 12 cm, BC = =
= 6 cm.
AB^2= (6√3)^2= 108
AC^2 = (12)^2 = 144 =
BC^2 = (6)^2 = 36
108 + 36 = 144
In a triangle, if the square of one side is equal to the sum of the squares of the remaining two sides, then the triangle is a right angled triangle.
In a right angled triangle, if one side is half of the hypotenuse then the angle opposite to that side is 30°.
Here, BC is half of AC.
Thus measure of angle A is 30°
