We can use trigonometry. The cosine of 15 will be the side adjacent to the 15-degree side (the one we are looking for) divided by 20, the hypotenuse. As cos(15) is about .966, we get 19.32 as the side we are looking for.
If Sharon is 3 years younger, then it's s = 3-b. However, it's twice her brothers age, which makes the formula our final answer, A, or 
W−5129=2329
Step 1: Add 5129 to both sides.
(5129+2339)
w−5129+5129=2329+5129 =
w=7458
