Question

1) If cos A
cos A = 7/25 find the value of tan A + cot A​

Answer 1

Answer:

625/168

Step-by-step explanation:

cos A = 7/25

then , sin²A = 1– cos²A = 1 – (7/25)² = 1 – 49/625 = (625–49)/ 625 = 576/625

then , sin A = √sin² A = √(576/625) = 24/25

then, tan A = sin A / cos A = (24/25) / ( 7/25) = 24/7

cot A = 1/tan A = 7/24

therefore, tan A + cot A

= 24/7 + 7/24

= 625/168 (answer)

Answer 2

Answer:

cosA 7/25

b/h=7/25

p^2=h^2-b^2

p^2=25^2-7^2

p^2=625-49

p^2=576

p=√576

p=24

tanA+cotA

p/b+b/p=24/7+7/24
