Question

In triangle ABC, right angled at B, Find the expressions of cos A , sin C, tan A and cot C.

• A. AB/AC , BC/AC, BC/AB , AB/BC
• B. BC/AC , AB/AC, BC/AB , BC/AB
• C. AB/AC , AB/AC, BC/AB , BC/AB
• D. BC/AC , BC/AC, AB/BC , BC/AB

Answer 1

The correct option is C AB/AC , AB/AC, BC/AB , BC/AB


In $\Delta$ ABC,
Sin C = Opposite/hypogenous = AB/AC
cos A = adjacent/hypogenous = AB/AC
tanA = Opposite/adjacent = BC/AB
cot C = adjacent/Opposite = BC/AB
