Q. 7
If the sides of a triangle are proportional to 2, √6 and √3 – 1, find the measure of its greatest angle.
Answer :
Lets say
a = 2x, b=√6x and c=(√3-1)x
where x is any constant
Now by putting cosine law
By Cosine law,
Putting Cosine law for B,
Putting Cosine law for C,
So, The largest Angle is 120° i.e. ∠B
