Sin Q = oppo. / hypo
sin Q = 9/15
sin Q = 0.6
All you have to do is divide the ounces he has into how much he gives the dog each day so 128/8 is 16
Since complementary angles add to 90°, (4x - 1) and (5x + 19), also add to 90°.
Thus, lets form an equation:
90 = 5x + 19 + 4x - 1
72 = 9x
x = 9
Thus, the measure of angle B is 64°.
