Q:
Resolver las siguientes identidades trigonométricas 1. \( \boldsymbol{\operatorname { c o s } ( \alpha ) + \operatorname { s i n } ( \alpha ) \operatorname { t a n } ( \alpha ) = \operatorname { s e c } ( \alpha )} \) 2. \( 1-\sin (\alpha) \cos (\alpha) \tan (\alpha)=\cos ^{2} \propto \) 3. \( \cot ^{2} \alpha+1=\frac{1}{\operatorname{sen}^{2} \alpha} \)
Q:
8) En un triángulo rectángulo ABC ( \( \mathrm{m}<\mathrm{C}=90^{\circ} \) ), la longitud del lado más largo mide 82 m y la tangente de uno de sus ángulos agudos es \( \frac{9}{40} \) Determine el perimetro de dicho triángulo. 9) Resuelve las nronuntre i
Q:
(3.) Expresa la medida en radianes del ángulo \( \alpha \), menor que \( 360^{\circ} \), al que equivalen estos ángulos. \( \begin{array}{llll}\text { a. } 480^{\circ} & \text { b. }-1235^{\circ} & \text { c. } 930^{\circ} & \text { d. } 1440^{\circ}\end{array} \)
Q:
Convert each degree measure to radian measure. Ex- press the answer in terms of \( \pi \) and as a decimal approxi- mation rounded to the nearest hundredth. \( \begin{array}{ll}\text { 9. } 35^{\circ} & \text { 10. }-40^{\circ} \\ \begin{array}{ll}\text { 11. } 1080^{\circ} & \text { 12. } 154.5^{\circ} \\ \text { Convert each radian measure to degrees. Round an- } \\ \text { swers to the nearest tenth of a degree if necessary. } \\ \begin{array}{ll}\text { 13. } \frac{\pi}{5} & \text { 14. }-\frac{7 \pi}{2} \\ \text { 15. } \frac{\pi}{12} & 16.5\end{array}\end{array} .\end{array} \).
Q:
4. Halla los valores de las demás funciones trigonomé- tricas a partir de la función dada, con valores en el primer cuadrante. \( \begin{array}{lll}\text { a. } \tan t=\frac{3 \sqrt{3}}{2} & \text { b. } \cos t=\frac{1}{3} & \text { c. } \operatorname{cosec} t=2 \\ \text { d. } \operatorname{sen} t=\frac{1}{2} & \text { e. } \sec t=3 & \text { f. } \cot t=\frac{\sqrt{3}}{3}\end{array} \)
Q:
3. Encontrar 2 anguios positivos y dos negativos Coterminales para Cada uno de bos sigbientes angul - A. \( 50^{\circ} \quad B \cdot 260^{\circ} \quad \frac{c 7 \pi}{3} \quad d-\frac{1 \pi i}{6} \) A. A \( 50^{\circ}-360^{\circ}=-310-360=-670^{\circ} \) \( 50^{\circ}+360^{\circ}=410+360=770^{\circ} \) B \( 260^{\circ}-360=-100^{\circ}-360=-460^{\circ} \) \( 260^{\circ}+360=620+360=980^{\circ} \)
Q:
4alla los valores de las demás funciones trigonomé- tricas a partir de la función dada, con valores en el primer cuadrante. \( \begin{array}{lll}\text { a. } \tan t=\frac{3 \sqrt{3}}{2} & \text { b. } \cos t=\frac{1}{3} & \text { c. } \operatorname{cosec} t=2 \\ \text { d. } \operatorname{sen} t=\frac{1}{2} & \text { e. } \sec t=3 & \text { f. } \cot t=\frac{\sqrt{3}}{3}\end{array} \)

Q:
Question A boat is heading towards a lighthouse, whose beacon-light is 103 feet above the water. From point \( A \), the boat's crew measures the angle of elevation to the beacon, \( 6^{\circ} \), before they draw closer. They measure the angle of elevation a second time from point \( B \) at some later time to be 11. Find the distance from point \( A \) to point \( B \). Round your answer to the nearest tenth of a foot if necessary.
