Question

Find the value of cot A if sin A =1/2

Answer 1

Answer:

the answer is ✓3.......

Answer 2

Answer:

given that,

SinA=1/2

Sin =opposite side/hypotenuse

let hypotenuse be 2k and opposite side be k

by Pythagoras theorem ,

(2k)²=(k)²+x²

4k²=k²+x²

x²=4k²+k²

x²=5k²

x=√5k²

x=√5 k

third side=√5 k

cot A=adjacent side/opposite side

=k/√5 k

=1/√5

hope it works...............................™✌️ ✌️
