→since x &
have tRhe same
tick marks,
Sin 47
%3D
y
Sin47
y is also 8.20-
12
X Sin47= 6
Sin47 sinA7
Sin47= 8.20
Luna should have used a side length of 12
instead of 6.
Luna used the wrong trig function, she
should have used cosine.
Luna used the wrong trig function, she
should have used tangeant.
Luna used the wrong trig function, she
should have used INVERSE sine to solve for
х.
Luna set up her ratio / proportion
incorrectly, she should have put x in the
numerator and 6 in the denominator.
There is no mistake.
