Question

in cos A 12/13 then find sinA and tanA
​

Answer 1

Answer:

refer to the attachment

Answer 2

Answer:

cos A = 12/13

base = 12

hypo = 13

altitude = √(hypo^2 -base^2)

            = √( 13^2 - 12^2)

            =5

therefore

Sin A = 5/13

Tan A = 5/12  (answer )

if the answer is useful pls mark as brainliest ...plsssss
