Answer:
Step-by-step explanation:
=>3:15 :: 30:x
\begin{gathered}3 \times x = 15 \times 30 \\ 3x = 450 \\ x = \frac{450}{3} \\ x = 150 \: ans\end{gathered}
3×x=15×30
3x=450
x=
3
450
x=150ans

sin²θcosec(90°-θ) - cot²(90°-θ)cosθ = sin²θ/cosθ - tan²θ cosθ = sin²θ/cosθ - sin²θ/cosθ cos²θ
= sin²θ/cosθ - sin²θ/cosθ = 0
