5 1/2 - u = 9/4          U= 13/4

Basically you have to get the variable (u) by itself. Doing this by doing the opposite of what it’s doing to both sides of the equation.

Use the Law of Sines to find the measure of angle J to the nearest degree.
rjkz [21]
\bf \textit{Law of sines}
\\ \quad \\
\cfrac{sin(\measuredangle A)}{a}=\cfrac{sin(\measuredangle B)}{b}=\cfrac{sin(\measuredangle C)}{c}\\\\
-----------------------------\\\\
\cfrac{sin(J)}{9.1}=\cfrac{sin(97^o)}{11}\implies sin(J)=\cfrac{9.1\cdot sin(97^o)}{11}
\\\\\\
\textit{now taking }sin^{-1}\textit{ to both sides}
\\\\\\
sin^{-1}\left[ sin(J) \right]=sin^{-1}\left( \cfrac{9.1\cdot sin(97^o)}{11} \right)
\\\\\\
\measuredangle J=sin^{-1}\left( \cfrac{9.1\cdot sin(97^o)}{11} \right)

How are you can’t do that I want no which answer
Sav [38]

The area of the square is 14*14 = 168 ft^2.

The area of the circle is πr^2. The radius is diameter/2 = 7. The area of the circle is 3.14*(7)^2 = 3.14*49 = 153.86 ft^2.

The area of the shaded part is the area of the square minus the area of the circle = 168 - 153.86 = 14.14 ft^2.
