Resuelve la para cada uno de los siguientes diagramas. Nombra las relaciones que utilizaste. Muestra todo tu trabajo.  

  1. Two right triangles connected to each other, The smaller triangle's hypotenuse is the short leg of the larger triangle, The smaller triangle has legs of 3 and 4 meters, The larger triangle has a long leg of 12 meters, and a hypotenuse of, x.

    Usa el Teorema de Pitágoras para despejar la .

    Label of, y, added to the hypotenuse of the smaller right triangle & also the vertical leg of the large right triangle.

    Despues de despejar la , usa de nuevo el Teorema de Pitágoras para despejar la .

  1. A triangle where the left base angle is 35 degrees. The top vertex angle is 65 degrees. Two line segments parallel to the base extend first from the left side toward the left, creating an angle of 35 degrees; and the second segment from the right side toward the right creating an angle of x degrees, with the triangle sides, each angle below the line.

    Extiende las rectas paralelas que ya están dibujadas.

    A triangle with the base, a horizontal line starting from a point near the bottom right side of the triangle and going right, and another horizontal line starting near the top left of the triangle and going left, which are all parallel to each other. The bottom left angle is 35 degrees & the top angle is 65 degrees.

    Ahora establece una relación entre y uno de los ángulos que ya está dado.

    Usa los recuadros de Apuntes de matemáticas de las Lecciones 2.1.1 y 2.1.4 si necesitas ayuda para recordar las relaciones entre pares de ángulos.
