Answer:
Reinaldo es ingeniero
Step-by-step explanation:
Por los datos del problema sabemos que Jeferson es casado. También sabemos que el profesor se casará pronto, así que:
Jeferson no es profesor
Reinaldo debe tomar el metro para visitar al médico, así que no es vecino de ninguno. Como el médico y el profesor son vecinos, entonces Reinaldo no es médico ni profesor, asi que
Reinaldo es ingeniero
Podemos saber además que si Jeferson no es profesor (ya demostrado) ni tampoco es ingeniero, entonces
Jeferson es médico

Answer:
a = 5.07
Step-by-step explanation:
Here, we want to get the value of the side marked a
What we have is a right triangle
so, to find the value of a, we are to use the correct trigonometric ratio
The angle given faces a, which makes a the opposite
the side measure faces the right angle and that makes it the hypotenuse
The trigonometric ratio that connects the two is the sine
The sine is the ratio of the opposite to the hypotenuse
mathematically;
sine 25 = a/12
a = 12 * sine 25
a = 5.07
