Using one of the above equations, you can find the value of x.
tan x = 84/13 => x = tan-¹(84/13)
x = 81.20°
Hope that helps
$20.50 x .3 = 6.15
20.50 - 6.15 = $14.35
The book is now $14.35
<span>3xy+x=9
3xy = 9 - x
y = 3/x - 1/3
if x = 2
f(2) = 3/2 - 1/3
f(2) = 9/6 - 2/6
f(2) = 7/6
f(2) = 1 1/6</span>
Answer:
The answer is D since 5 rows of 6 is just 5x6 then they want all so multiple 3 to get the total
