Question

if tanA=-4/3,then secA is​

Answer 1

Step-by-step explanation:

tanA=-4/3

formula of tan =P/B

so we have to find h or hypotenuse

h=5

sec =h/b

secA =5/3

Answer 2

$\to$ Sec A = 5/3

$\large \bold{ \underline{ \underline{ \: Explaination : \: \: \: }}}$

Given ,

$\star$ Tan A = - 4/3 = P/B

$\star$ Perpendicular (P) = - 4

$\star$ Base (B) = 3

By Pythagoras theorem

$\to$ H² = P² + B²

$\to$ H² = (-4)² + (3)²

$\to$ H² = 16 + 9

$\to$ H² = 25

$\to$ H = 5

$\therefore$ Sec A = 5/3 = H/B
