Answer:
x = 55.6
Step-by-step explanation:
Recall the 3 main trig functions
Sin = opposite / hypotenuse
Cos = adjacent / hypotenuse
Tan = opposite / adjacent
Note that hypotenuse = longest side length
We want to find angle "x".
We are given its opposite side length ( 19 ) as well as the adjacent side length
When dealing with the opposite and adjacent we use tan
Tan = Opp / Adj
Opp = 19 and Adj = 13
Tan(x) = 19/13
* take the inverse tan of both sides *
x = 55.6

bro i'm not too sure we can help you with this..
The area of the circle would be pi r^2 and the area of the square will be side^2. r is 12 and the side is 12rad(2). the circle would have an area of 144 pi and the square an area of 288. so 452.39-288 =164.4
