The legs of a 45-45-90 triangle have a length of eight units. What is the length of its hypotenuse?

1 answer:

6 0

The hypotenuse of a 45 45 90 triangle equals one of the legs times the square root of 2
hypotenuse = 8 * 1.4142135624 
hypotenuse = 11.3137084990

Given that the product of two positive integers is 44, and their least common multiple is 22, what is their greatest common divi

Answer:

Step-by-step explanation:

For any positive numbers a,b we always have the following identity:

$a\cdot b=gcd(a,b)\cdot lcm(a,b)$

(gcd(a,b) denotes the greatest common divisor between a and b, and lcm(a,b) denotes the least common multiple between a and b)

In our case, we are given that $a\cdot b = 44$ and that $lcm(a,b)=22$ . Plugging that in into our identity, we get:

$44=gcd(a,b)\cdot 22$

And so solving for $gcd(a,b)$ :

$gcd(a,b)=\frac{44}{22}=2$
