Question

If tanA=3/4, find the values of secA and cosA.​

Answer 1

Answer:

sec A = 5/4.

cos A = 4/5.

Hope it helps you!

Answer 2

Answer:

tanA=3/4=perpendicular (p)/base(b)

P=3 $ b=4 hence, h=√p^2+b^2 =5

CosecA=h/p, secA=h/b

Since,tanA will be +ve only in 1st $3rd quadrant,

Hence possible value of CosecA=+5/3 or - 5/3 and secA=+5/4 or -5/4 , because in 3rd quadrant cosec and sec are negative..
