Question

In a ∠ABC, B = 90°, AB = 5 cm and BC = 7 cm. Find the value of tan A - cot C.

Answer 1

Given :


AB= 5 cm , BC= 7cm


tanA = perpendicular/base= BC/AB


tan A = 7/5



cot C= base / perpendicular= BC/AB


cot C= 7/5



tan A - cot C


7/5 - 7/5 = 0



tan A - cot C = 0


The value of tan A - cot C = 0

Answer 2

Hi friend,

Your answer:


tanA = perpendicular/base
         
        = BC/AB

        = 7/5


cot C = base / perpendicular

         = BC/AB

          = 7/5

Now,
tan A - cot C = 7/5 - 7/5 = 0


Hence, the value of tan A - cot C = 0

Hope it helps!
