Question

if tan A 1/√3,find value of skin A​

Answer 1

Answer:

Sin A=1/2

answer for the given problem is given in different ways

Step-by-step explanation:

Given that:-

Tan A=1/√3

=>Tan A=Tan 30°

=>A=30°

Now ,Sin A

=Sin 30°

=1/2

Sin A=1/2

-----------------------------------

or

Given that

Tan A=1/√3

Cot A=/1 Tan A

=>Cot A=√3

=>Cot A=Cot 30°

=>A=30°

Sin A=Sin 30°=1/2

Sin A=1/2

--------------------------------------

or

Tan A=1/√3

Cot A=√3

we know that

Cosec²A- Cot² A=1

=>Cosec²A-(√3)²=1

=>Cosec²A-3=1

=>Cosec²A=1+3

=>Cosec²A=4

Cosec A=√4

=>Cosec A=2

=>Sin A=1/2

---------------------------------------
