eduard

Answer:

180 ft

Step-by-step explanation:

We are working to find the perimeter here. Let x represent the length of the room.

We know that the formula to find the perimeter of something is 2L + 2W = P. Here, we know the required perimeter and the width of the room.

Our equation is now: 2x + 2(70) = 500

Now we have to find x, we'll start by multiplying 70 by 2.

2x + 140 = 500

Now we can solve for x:

Subtract 140 from both sides

2x = 360

x = 180

The length of this room is 180 ft.

2(180) + 140 = 500

360 + 140 = 500

En un triángulo obtusángulo, uno de los ángulos mide 20° mas que el otro. El tercer ángulo, mide el doble que el mayor de los do
Troyanec [42]

Answer:

La medida del primer ángulo es 30°, la medida del segundo ángulo es 50° y  el tercer ángulo mide 100°.

Step-by-step explanation:

Siendo "x" el valor de un ángulo del triángulo obtusángulo, sabes que uno de los ángulos, llamado segundo ángulo, mide 20° más que el primero. Este segundo ángulo se representa como x + 20°.

Además, un tercer ángulo mide el doble que el mayor de los dos, que en este caso es el ángulo cuya expresión es x + 20°. Por lo que el doble de este será 2*(x + 20)°, que será la medida del tercer ángulo.

Teniendo en cuenta que la suma de los ángulos interiores de un triángulo es 180°. Entonces, es posible sumar los valores de cada uno de los ángulos e igualarlos a 180°:

x + x + 20° + 2*(x + 20°) = 180°

Resolviendo:

x + x + 20° + 2*x + 2*20° = 180°

x + x + 20° + 2*x + 40° = 180°

4*x + 20° + 40° = 180°

4*x + 60° = 180°

4*x = 180° - 60°

4*x = 120°

x = 120° ÷ 4

x = 30°

Entonces, la medida del primer ángulo es 30°. El segundo ángulo es calculado como x + 20° = 30° + 20° = 50° mientras que  el tercer ángulo es 2*(x + 20°) = 2*(30° + 20°) = 2*(50°) = 100°

<u><em>La medida del primer ángulo es 30°, la medida del segundo ángulo es 50° y  el tercer ángulo mide 100°.</em></u>
