35 km 21 km b What is the length of the missing leg? b = kilometers

marta [7]

Answer:

28 km

Step-by-step explanation:

One leg = 35 km

Second leg = 21 km

We need to find the length of the missing leg. Using Pythagoras theorem, we can find it.

Hypotenuse² = base² + perpendicular²

$x=\sqrt{35^{2}-21^{2}}\\\\x=28\ km$

So, the length of the missing leg is equal to 28 km.

the sum of two numbers is 9. if one number is subtracted from the other, the result is 3. find the numbers

irakobra [83]

X, y - the numbers

The sum of the two numbers is 9.
$x+y=9$

If one number is subtracted from the other, the result is 3.
$x-y=3$

Solve the system of equations:
$x+y=9 \\
\underline{x-y=3} \\
x+x=9+3 \\
2x=12 \ \ \ |\div 2 \\
x=6 \\ \\
x+y=9 \\
6+y=9 \ \ \ |-6 \\
y=3$

The numbers are 6 and 3.
