9) Shown below is a problem that a 1 point student did work on and submitted. They were asked to solve for x and y. What was the students mistake, if any? * Luna Villarreal Monday, March 1, 2021 341 PM →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.
