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 isthe hypotenuse is (3√2)/2

Answer:
Step-by-step explanation:
First you divide the total mulch (77 1/2) by the amount per bag (2 1/4). This will tell you how many bags of mulch you have.
The answer is 34.4444444 which is 34 full bags of mulch.
Now if one bag is $2.25, then what is 34 bags?
$2.25 multiplied by 34 is $76.5
Hope this helps your understanding
Answer:
214
Step-by-step explanation:
set bc = to cd and solve for x
then substitute x into one of the equations and solve --> you should get 73
multiply 73 by 2 and then subtract that from 360
you should get 214
