An aircraft flies 500 km on a bearing of \( 100^{\circ} \) and then 600 km on a bearing of \( 160^{\circ} \). Find the distance and bearing of the finishing point from the starting point.

Define the tangent function using an example from a specific right triangle with known angles and side lengths.

\( a=7, b=5, c=3 \). Find \( \angle A \)

Dado un triángulo de 30°-60° donde la hipotenusa mide 12 cm, calcula la longitud del cateto opuesto al ángulo de 60°.

4. (s) Diben \( \operatorname{lan} \theta=-1.4826 \) dan \( 180^{\circ} \leq \theta \leq 360^{\circ} \) hilung sudul \( \theta \) Given than \( \tan \theta=-1.4826 \) ond \( 180^{\circ} \leq 0 \leq 360^{\circ} \). calculate angle \( \theta \)

23. El menor valor del ángulo \( x\left(0^{\circ} \leq x<180^{\circ}\right) \) que satisface la ecuación trigonométrica \( \cos ^{2}(x)-3 \cdot \operatorname{sen}^{2}(x)=0 \) es: A. \( 120^{\circ} \) B. \( 30^{\circ} \) C. \( 150^{\circ} \) D. \( 60^{\circ} \)
