tan(70)=12cm/y The tangent of the angle equals the opposite over the adjacent

y=12cm/tan(70) Isolate y and plug into calculator

y = 4.4 cm (Rounded to the nearest tenth)

wouldn't it be 7.2 because you have 2 sides which equal 144 and the 2 angles are 90 and 70 and when you subtract them, you get 20. So, 144/20= 7.2. I am just guessing.
