Question

Cot 5theta=tan 10theta calculate the value of 5theta​

Answer 1

Answer:

5theta = 30

Step-by-step explanation:

Cot 5theta = tan10theta

As we know,

Cot theta = tan(90-theta)

So,

tan(90-5theta) = tan(10theta)

90-5theta = 10theta

90 = 10theta + 5theta

90 = 15theta

90/15 = theta

6 = theta

Multiplying 5 on both sides:-

6*5 = theta*5

30 = 5theta

Hence, 5theta = 30
