Question:

cos235° + cos 55° . sin 35° + $\frac{tan 34°}{cot 56°}$ = ____________ .

Options:

2

3

4

1

Correct Answer:

2

Explanation:

cos235° + cos 55° . sin 35° + $\frac{tan 34°}{cot 56°}$

cos55° = sin35°, tan34°= cot56°

= cos²35° + sin²35° + $\frac{tan34°}{tan34°}$

(cos²A + sin²A = 1)

= 1 + 1 =
