In an equilateral triangle ABC , match the following ratios to the values
Trignometric ratiosValues(i)tan 60∘(a)1√3(ii)cot 30∘(b)√3(iii)cosec 30∘(c)2(iv)sec 30∘(d)2√3
(i) –b , (ii) – b , (iii) – c , (iv) – d
Let each side of the equilateral triangle be a.
Length of perpendicular AD = √3a2
tan 60 = tan B = ADBD = √3
cot 30 = cot A2 = ADBD = √3
cosec 30 = cosec A2 = ABBD = 2
sec 30 = sec A2 = ABAD = 2√3
