Answer:
<em>Trabajó 3 horas al día</em>
Step-by-step explanation:
<u>Proporcionalidad</u>
Una persona planeó terminar la obra en 15 dias, pero tardó 10 dias adicionales porque trabajó 2 horas menos por día.
Usaremos proporciones para calcular las horas de trabajo diarias.
Si 2 horas diarias representan 10 dias de atraso, entonces cada hora representa 5 dias de trabajo.
Si la obra tardaba 15 dias, entonces la persona trabajó 15/5 = 3 horas diarias.

Step-by-step explanation:
Graph y=|x|
Note that the graph is shaped like a V. The left half of the graph is decreasing from -∞ up until 0 when it hits the origin and starts to increase. Put this into interval notation: (-∞,0).
Answer:
By hypotenuse - side test (HL) the two triangles are congruent.
Step-by-step explanation:
In ∆ABC and ∆DCB
i) angleABC = angleDCB.....(each 90°)
ii) BC = BC .....( common side)
iii) AC = DB.....(given)
therefore by hypo-side test ∆ABC congruent ∆DCB
obtuse because it all adds up to 180 degrees
