Question

if tan a=4/3 then find cos a​

Answer 1

Answer:

3

Explanation:

tan a = sin a / cos a

4/3 = Sina / cos a

therefore, cos a = 3

Answer 2

Answer:

tan a = 4/3

1 +tan²a = sec²a

1 + 4²/3² = sec²a

1 +16/9 = sec²a

9/9+16/9 = sec²a

25/9 =sec²a

5/3 =sec a

1 / sec a= cos a

1/ (5/3) = cos a

3/5 = cos a
