Question

 If CosA=1/2, then Value of SecA-CosA is


​

Answer 1

Step-by-step explanation:

sec a = 1/cos a

sec a=2

sec a - cos a

2-1/2

3/2

Answer 2

Answer:

cosA = 1/2

cos A = b/h= 1/2

so , base = 1 and hypotenuse = 2

by Pythagores theorem

h^2 = p^2 + b^2

2^2 = p^2 + 1^2

4 -1 = p^2

√3 = p

now , secA - cosA

h/b- b/h

2/1 - 1/2

3/2
