Answer:

You multiply 5 by 1/5 to get 1. So with 2x, you multiply by 1/(2x) to get 1. That's about all you know, since we only know that x is positive.

Answer:

$\frac{25}{10x-1}$

Step-by-step explanation:

The multiplicative inverse of "a" is " $\frac{1}{a}$ "

a × $\frac{1}{a}$ = 1

~~~~~~~~~~~

$\frac{1}{5}$ ( 2x - $\frac{1}{5}$ ) = $\frac{2}{5}$ x - $\frac{1}{25}$

1 ÷ ( $\frac{2}{5}$ x - $\frac{1}{25}$ ) = 1 ÷ ( $\frac{10x}{25}$ - $\frac{1}{25}$ ) = 1 ÷ ( $\frac{10x - 1}{25}$ ) = $\frac{25}{10x-1}$

The multiplicative inverse of the product is $\frac{25}{10x-1}$

If the given values in a right triangle are cos A =

Vlad1618 [11]

See the picture attached to better understand the problem

we know that
in the right triangle ABC
cos A=AC/AB
cos A=1/3
so
1/3=AC/AB----->AB=3*AC-----> square----> AB²=9*AC²----> equation 1

applying the Pythagoras Theorem
BC²+AC²=AB²-----> 2²+AC²=AB²---> 4+AC²=AB²----> equation 2

substitute equation 1 in equation 2
4+AC²=9*AC²----> 8*AC²=4----> AC²=1/2----> AC=√2/2
so
AB²=9*AC²----> AB²=9*(√2/2)²----> AB=(3√2)/2

the answer is
the hypotenuse is (3√2)/2
