We know the area is length * width.
So we know the length is 8 feet.
The width is 7 + x feet.
Multiply them:
8 * 7 + x.
56 + x.
So option D)
sorry, I misread the options! I meant D) not A)
We have that
tan x=5
we know that
tan x =sin x/ cos x
sin x/ cos x=5------> squaring-----> sin² x/cos² x=25
remember that
sin² x+cos² x=1-----> cos² x=1-sin² x
substitute
sin² x/[1-sin² x]=25
sin² x=25-25*sin² x
26*sin² x=25
sin² x=25/26
sin x=5/√26
cos² x=1-(5/√26)²----> 1-(25/26)----> 1/26
cos x=1/√26
the answers are
sin x=5/√26
cos x=1/√26
Answer:
30m-30m+40 equals 40
i think thats the right answer
Step-by-step explanation:
Answer:
<h2><em><u>x = 5</u></em></h2>
Explanation:
11 - x < 7
- 11 minus a number is less than 7
<em>Insert 5 into the equation</em>
11 - 5 < 7
<em>Simplify</em>
6 < 7
<em>Insert 3 into the equation</em>
11 - 3 < 7
<em>Simplify</em>
8 < 7
<h3><u><em>x = 5 is a solution to the equation 11 - x </em></u><u>< 7</u></h3><h3><u /></h3>
