Question

Find the value of k if tan (15 minus k)degrees equals cot (2k + 60)degrees.

Answer this question with step by step solutions.

Answer 1

Answer:15Step-by-step explanation

tan(15-k)°=cot(2k+60)°

tan(15-k)°=tan{90-(2k+60)°}

cancelling tan from both sides, (15-k)=(90-2k-60°)

15-k=30-2k

-k+2k=30-15

k=15

therefore value of k=15
