Question

If $tan space A plus tan space B plus tan space C equals 3 square root of 3$ then the Δ^k is

isosceles
right angled
equilateral
scalene

The correct answer is:
equilateral

If $tan space A plus tan space B plus tan space C equals 3 square root of 3$ then the Δ is equilateral bcz of
tanA = tanB = tan C= $square root of 3$
[ $tan space straight pi over 3 space equals space square root of space 3 space end root.
