Answer:

b =28.28

Step-by-step explanation:

SinA/x = sinB/x

Sin30°/20=sin45°/b

Cross multiplication

20×sin45=b×sin30

20×sin45/sin30 =b

b=28.28

The point-slope form:

$y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (-8, -8) and (-7, 9). Substitute to the formula of a slope:

$m=\dfrac{9-(-8)}{-7-(-8)}=\dfrac{17}{1}=17$

Put the coordinates of the point (-7, 9) and the value of slope to the point-slope formula:

$y-9=17(x-(-7))\\\\\boxed{y-9=17(x+7)}$
