Question

if tanA = 3 cot A then find the value of A
a) 15°
b) 30°
c) 45°
d) 60°​

Answer 1

Answer:

d)60°

Step-by-step explanation:

tanA=3cotA;

tanA/cotA=3;

tan^(2)A=3;

{tanA=1/cotA]

tanA=√3;

then A=60°

Answer 2

answer is A=60°

tanA=3cotA

tanA/cotA=3

sinA/cosA/cosA/sinA=3

sinA^2/cosA^2=3

tanA^2=3

tan60=

$\sqrt{3}$

so, tanA^2=3
