Question

find a if Cot a=tan(210-3a)​

Answer 1

Answer:

Answer is as follows:-

Step-by-step explanation:

Since, if Cot a = tan (210-3a)

tan(90⁰-a)= tan (210-3a)

90-a =210-3a

3a -a=210-90

2a =120

a =120/2

a =60

Answer 2

Here is your answer....

cot a = tan (210-3a)

tan (90-a)= tan (210-3a) tan (90-a)= cot a

.: By comparision

90- a = 210-3a

210-90 = 3a - a

120 = 2a

a= 60

Therefore a is 60.
