Question

If cos A=12/13 then find the sinA and tan A

Answer 1

Answer:

sin theta = 17/13

Tan theta =17/12

Step-by-step explanation:

cos theta = base/ hypotaneus

By using Pythagoras theorem ,

H²= B²+ P²

P =√(12)²+(13)²

P= √313 = 17.69 ~ 17

sin theta = perpendicular / Hypotaneus

Therefore , sin theta = 17/13

Tan theta = sin theta / cos theta or Perpendicular/ base

Tan theta = 17/12
