Answer:
-15/17
Step-by-step explanation:
One method is to use Pythagorean identity.
sin² θ + cos² θ = 1
sin² θ + (-8/17)² = 1
sin² θ + 64/289 = 1
sin² θ = 225/289
sin θ = ±15/17
Since θ is in the third quadrant, sin θ < 0. So sin θ= -15/17.
Another method is to draw a triangle in the third quadrant, with angle θ, adjacent side -8, and hypotenuse 17. Use Pythagorean theorem to find the opposite side:
c² = a² + b²
17² = (-8)² + b²
b = -15
Therefore, sin θ = -15/17
Add up 2, 1 and 3. Result: 6.
Mother received 2 parts out of 6, or (2/6)(18) = 6 apples;
Father rec'd 1 part out of 6, or (1/6)(18) = 3 apples, and Julia herself rec'd (3/6)(18), or 9, apples.
