A Dermine la derivada do la fonción. \( f(x)=2-5 x^{3} \)

7- In triangle \( P Q R \), the measure of angle \( P \) is \( (3 x+5)^{\circ} \). The measure of angle \( Q \) is \( (2 x+9)^{\circ} \), and the measure of angle \( R \) is \( (4 y+5)^{\circ} \). If side \( Q R \) is extended through point \( R \) to point \( S \), and the measure of angle \( P R S \) is \( (x+y)^{\circ} \). What is the value of \( x+y \) ?
