Multiply by 4 on both sides. This results into:

24 = a + 8

If 8 is substracted in both sides then a would be:

16 = a

What is the length of a hypotenuse when the legs are 5 and 12
Alisiya [41]
By using pythagoras theorem where
(Base)^2 +(perpedicular)^2 = (hypotenuse)^2
So,
(5)^2 +(12)^2 = (hypotenuse)^2
25 + 144 = (hypotenuse)^2
169 = (hypotenuse)^2
13 = hypotenuse


So, hypotenuse = 13

What is the value of x?
nika2105 [10]

AC is the hypotenuse of triangle ABC.

Because the length is 6√2 and angle A is 45 degrees, we know the length of both sides is 6.

This means AB is 6, which it the hypotenuse of triangle BCD.

Using cos(angle) = adjacent leg / hypotenuse we can find x:

cos(60) = X / 6

x = 6 * cos(60)

x = 3

The area of a rectangular wall of a barn is 108 square feet. Its length is 12 feet longer than the width. Find the length and wi
forsale [732]
Area = Width x Length
Area = 108
Square root of 108 = 10.4

108/ 9 = 12      ...12 is not 12 larger than 9
108/ 6 = 18      ...18 is 12 larger than 6

108 = 6 x 18

Width = 6
Length = 18

La montaña más alta del mundo es Everest cuya altura es de 8.848m y la altura de la segunda montaña más alta es de 2hm 3dam y 7m
olchik [2.2K]

Answer:

La segunda montaña más alta del mundo tiene 8611 metros.

Step-by-step explanation:

La montaña más alta del mundo es Everest cuya altura es de 8.848m.

La altura de la segunda montaña más alta es de 2hm 3dam y 7m menos. Para calcular la altura que tiene la segunda montaña más alta del mundo, debes realizar primero un cambio de unidades sabiendo que

  • 1 hm= 100 m
  • 1 dam= 10 m

Entonces podes aplicar las siguientes reglas de tres simple:

Si 1 hm equivale a 100 m, 2 hm equivale a ¿Cuántos metros?

metros=\frac{2 hm*100 m}{1 hm}

metros= 200

Si 1 dam equivale a 10 m, 3 dam equivale a ¿Cuántos metros?

metros=\frac{3 dam*10 m}{1 dam}

metros=  30

Entonces, la altura de la segunda montaña más alta es de 200 m+30 m+ 7 m menos que el Everest. Esto es, 237 metros menos que la montaña más alta del mundo. Entonces:

8848 metros - 237 metros= 8611 metros

<u><em>La segunda montaña más alta del mundo tiene 8611 metros.</em></u>
