Step-by-step explanation:
Hello There!
We can find y by using trigonometric ratios
sine, cosine and tangent
![tan= \frac{opposite}{adjacent}](/tpl/images/2254/9303/d5295.png)
the opposite of the angle that has a measure of 28 degrees is y and the side that is adjacent to the angle is 35
so...
![tan28=\frac{y}{35}](/tpl/images/2254/9303/bbba5.png)
now we solve for y using basic algebra
we want to isolate the variable (y) using inverse operations
to get rid of the 35 we multiply each side by 35
![\frac{y}{35} =y\\tan28*35=35tan28](/tpl/images/2254/9303/3f633.png)
now we let the calculator do the rest of the work
![35tan(28)=18.60983011](/tpl/images/2254/9303/5ddb5.png)
*round to the nearest thousandth*
we're left with
y = 18.610
hence your answer is B
