Step-by-step explanation:
u.v=|u||v|cos60°
u.v=(2.5)(3.2)(1/2)
u.v=(8)(1/2)
u.v=4
In the expression 4(x), 4 represents the number of legs, and x represents the height of the coffee table.
Altogether this expression shows the total length of all legs from the coffee table and kitchen table combined.
<span>x + 1/2 = 3/4
</span><span>x + 2/4 = 3/4
x = 3/4 - 2/4
x = 1/4
answer
</span><span>x = 1/4</span>
