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.

  • geometry - ,

    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.
