Find each measure using the given measures of triangleXYZ. Round angle measures to the nearest degree and side measures to the nearest tenth. Find measure of angle Y if y= 7,z=11,and the measure of angle Z=37.

The Law of Sines:
sinY/y = sinZ/z,
sinY/7 = sin37/11,
Multiply both sides by 7:
sinY = 7*sin37 / 11,
sinY = 0.3830,
Y = 22.5 DEG.
