Answer:

A. 38\ \text{grados}

Step-by-step explanation:

La temperatura en Moscú es de 13 grados bajo cero. Entonces, la temperatura es de -13 grados.

La temperatura en Buenos Aires es de 25 grados bajo cero. Entonces, la temperatura es de 25 grados.

La diferencia de temperatura entre las dos ciudades es

25-(-13)=38\ \text{grados}

La diferencia de temperatura entre las dos ciudades en un momento dado es  38\ \text{grados}.

What is the area of the triangle?<br> 16<br> 8<br> 10
sertanlavr [38]

Answer:

64

Step-by-step explanation:

Find the area of both triangles inside the bigger triangle and add them together.

Use the Pythagorean theorem to find the missing length of the leg in the smallest triangle:

a² + b² = c²

8² + b² = 10²

64 + b² = 100

36 = b²

6 = b

Calculate the area of the smaller triangle:

1/2(<em>b</em>x<em>h</em>)

1/2(6 x 8)

1/2(48)

24

Calculate the area of the bigger triangle:

<em>We know that the longer leg is 10 units because we were able to subtract the length of the smaller triangle's leg from 16.</em>

1/2(<em>b</em>x<em>h</em>)

1/2(10 x 8)

1/2(80)

40

Add both areas to find the area of the largest triangle:

40 + 24 = 64
