We have a right triangle with a 15m hypotenuse and a 8m leg. If we use x for the missing leg then the Pythagorean Theorem states that:

$15^2=8^2+x^2$

Then we have to solve that equation for x:

$\begin{gathered} x^2=15^2-8^2=225-64 \\ x^2=161 \\ x=\sqrt[]{161} \end{gathered}$

So the answer is the square root of 161.

Tanzania [10]

Answer:

10 feet

Step-by-step explanation:

define variables:

y= height of the boards

x= distance to corner

we are trying to figure out what x is since we know the height of the board

4= 0.4x

divide both sides by 0.4

10=x

Calcula la longitud en YARDAS de

tatiyna

Answer:

Las longitudes solicitadas en yardas son:

Trayecto A = 109.361 yardas.
Trayecto B = 20.231785 yardas.

Step-by-step explanation:

Para hacer la conversión de unidades que requieres en el ejercicio, debes saber que:

1 metro = 1.09361 yardas

Con ese factor de conversión tú puedes hacer reglas de tres para calcular las medidas que requieres. En el caso del trayecto A:

Si:

1 metro = 1.09361 yardas
100 metros = X

Entonces:

$x=\frac{100m *1.09361yardas}{1m}$

Cancelamos metros y obtenemos:

x = 100 * 1.09361 yardas
x = 109.361 yardas

En este caso, el trayecto A en yardas corresponde a 109.361 yardas. El mismo procedimiento puede aplicarse para el trayecto B:

Si:

1 metro = 1.09361 yardas
18.50 metros = X

Entonces:

$x = \frac{18.50m*1.09361yardas}{1m}$

Cuando se cancelan los metros se obtiene:

x = 18.50 * 1.09361 yardas
x = 20.231785 yardas

Así, el trayecto B en yardas corresponde a 20.231785 yardas.

The coldest temperature recorded in Alaska was –80°F. This was 10°F warmer than the coldest temperature recorded in Siberia. Whi

Klio2033 [76]

The equation that can be used to find the coldest temperature recorded in Siberia is y + 10 = -80

Let the coldest temperature in Alaska be x

The coldest temperature recorded in Alaska was –80°F

x = –80°F

Let the coldest temperature in Siberia be y

The coldest temperature recorded in Alaska was 10°F warmer than the coldest temperature recorded in Siberia

This can be interpreted as:

Coldest temperature in Alaska = Coldest temperature in Siberia + 10

x = y + 10................(*)

Since x = -80

Substitute x = -80 into equation (*)

-80 = y + 10

This can be re-written as:

y + 10 = -80

The equation that can be used to find the coldest temperature recorded in Siberia is y + 10 = -80
