Question

if cosA= 7/15 then find the value of sec ^2A ​

please give proper answer

Answer 1

Answer:

225/49

Step-by-step explanation:

It is given that cosA = 7/15

then secA = 1/cosA = 15/7

sec²A = (15/7)²

sec²A = 225/49

Answer 2

Answer:

cosA= 7/25

Therefore,

Base =7 and Hypotenuse =25

Therefore, Perpendicular = √25² - 7² =√625−49 = √576 =24

Hence,

tanA + cotA = 24/7 + 7/24 = 576+49/168 = 625/168
