35 points: trigonometry
find each side marked with a letter. all lengths are in centimetres.

show the working since i know the answers.

Find Y using the law of cosines:

cos(angle) = adjacent leg / hypotenuse

cos(20) = 11/y

y = 11/ cos(20)

y = 11.706 ( Round answer as needed)

Find X using the law of sines:

Sin(angle) = opposite leg / hypotenuse

Sin(35) = 11.706 / X

X = 11.706 / sin(35)

X = 20.4088 ( Round answer as needed)

i believe a. 12x≥120 is the answer
