Question

If 3 cot A=4,then the value of sec A will be :
A)3/4
B)5/4
C)2/3
D)3/2

Answer 1

so option B is the correct one

Answer 2

Answer:

B) is correct        $\sec A=5/4$

Step-by-step explanation:

Given,

$3\cot A=4$

$\cot A=4/3$                   (  $\cot A=b/p$)

b=4,  p=3

$h=\sqrt{b^{2}+p^{2}}$

$h=\sqrt{4^{2}+3^{2}}=5$

$\sec A=h/b$

$\sec A=5/4$
