1. Un avión que se aproxima a un acuerdo. Observa la pista a un ángulo de depresión de \( 25^{\circ} \). Si el avión está a una altura de 15,000 pies, ¿ qué tan lejos (distancia del suelo ) está el avión en la pista?

Solve \( 2 \sin ^{2}(t)+\sin (t)-1=0 \) for all solutions \( 0 \leq t<2 \pi \) \( t=\square \) Give your answers as a list separated by commas

Solve \( 6 \cos ^{2}(t)-5 \cos (t)+1=0 \) for all solutions \( 0 \leq t<2 \pi \) \( t=\square \) Give your answers accurate to 2 decimal places, as a list separated by commas

Solve: \( \quad 0^{\circ} \leq x \leq 90^{\circ} \) \( \tan \left(x+100^{\circ}\right)=\tan x \cdot \tan (x+50) \cdot \tan (x-50) \)

Solve \( 3 \sin ^{2}(w)-10 \sin (w)+3=0 \) for all solutions \( 0 \leq w<2 \pi \) \( w=\square \) Give your answers accurate to 2 decimal places, as a list separated by commas

Find all solutions of the equation. \( \sin x=-\frac{\sqrt{3}}{2} \)
