Answer: El otro ángulo agudo tambien mide 45°.

Step-by-step explanation:

Supongo que en este caso nos referimos a un triangulo rectángulo.

Donde el triangulo rectángulo es aquel cuyo uno de sus ángulos es igual a 90°.

Los triángulos tienen una propiedad muy útil en estos casos, la propiedad es que la suma de todos los ángulos internos de un triangulo es siempre igual a 180°.

En este caso, sabemos que uno de los ángulos es 90° (por que es un triangulo rectángulo) y sabemos que uno de los otros ángulos es igual a 45° (lo dice el enunciado)

Entonces, si el ángulo faltante es X, tenemos la ecuación:

X + 90° + 45° = 180°

La resolvemos para X

X = 180° - 90° - 45° = 45°

Entonces el otro ángulo agudo de nuestro triangulo rectángulo es igual a 45°.

Jen Butler has been pricing​ Speed-Pass train fares for a group trip to New York. Three adults and four children must pay $ 132.
laiz [17]
Let a=price of adult ticket
let c=price of a child's ticket
start out by writing the following system of equations:
3a+4c=132
2a+3c=94
then, multiply the first equation by 2, and the second equation by 3 to get the following system of equations:
6a+8c=264
6a+9c=282
subtract the like terms to get the following equation:
-c=-18
divide both sides by -1 to get rid of the negative to get the price of a child's ticket to be $18. to find the price of an adult ticket, pick one of the original equations to substitute the 18 in for c to find a. for example:
2a+3c=94
2a+3(18)=94
2a+54=94
-54 -54
2a=40
2 2
a=20

or if you decide to use the other equation:
3a+4c=132
3a+4(18)=132
3a+72=132
-72 -72
3a=60
3 3
a=20
either way, you still get an adults ticket to be $20 and a child's ticket to be $18.

PLEASE HELP!!! <br> find the length of arc LN. Round to the nearest hundredth.<br> SHOW WORK....
patriot [66]

9514 1404 393

Answer:

  15.71 units

Step-by-step explanation:

The arc length is given by the formula ...

  s = rθ

where r represents the radius, and θ represents the central angle in radians.

The angle of 60° is π/3 radians, so the arc length is ...

  s = 15(π/3) = 5π ≈ 15.71 . . . units

  LN ≈ 15.71 units

__

<em>Note</em>: if you use 3.14 for π, you will get 15.70.
