Question

if tan tita =3apon 4 ,then find sec tita and cos tita​

Answer 1

Answer:

5/4 & 4/5

Step-by-step explanation:

tanA = 3/4

Square on both sides:

=> tan²A = (3/4)² = 9/16

=> sec²A - 1 = 9/16

=> sec²A = 9/16 + 1 = 25/16

=> secA = √(25/15) = 5/4

Hence,

secA = 1/cosA = 5/4

=> cosA = 4/5
