3. En un triángulo rectángulo, uno de los ca- tetos mide 5 centímetros más el doble del otro. Si la hipotenusa mide 85 centímetros, ¿cuánto mide cada uno de los catetos?

Directions: Answer the following word problems by making a diagram and including units in your answer. Show all your work to receive full credit. 16. LADDER A 10-foot ladder is leaning against a house. The base of the ladder is 5 feet from the side of the house. At what height does the ladder touch the house? Round to the nearest tenth if necessary.

17. ROSEs The Garden club has a garden in the shape of a right triangle, If one leg is 16 feet long and the hypotenuse is 20 feet long, how long is the remaining leg, along which the roses are planted? Round to the nearest tenth if necessary.

A point \( B(-4,4) \) is rotated \( 90^{\circ} \) clockwise about the origin. FInc (A) \( (4,4) \) (B) \( (3,2) \) (C) \( (-3,2) \) (D) \( (4,-4) \)

\( \begin{array}{lccc}\text { El área } & \text { del } & \text { paralelogramo } \\ \text { formado } & \text { por } & \text { el } & \text { vector } \\ \vec{A}=3 i- & j-2 k & \text { y } & \text { el } \\ \text { vector } & \vec{B}= & -2 j-3 k \\ \text { equivale a } & & \end{array} \)

Analyze the equation. That is, find the center, vertices, and foci of the ellipse and graph it. \[ \frac{x^{2}}{49}+\frac{y^{2}}{4}=1 \]
