Answer:
y = 2x -4
Step-by-step explanation:
The coefficient of x in the given equation is the slope of the line. A perpendicular line will have a slope that is the opposite reciprocal:
-1/(-1/2) = 2
The point-slope form of the equation of a line can be used to find the desired equation:
y -y1 = m(x -x1) . . . . . . line through (x1, y1) with slope m
For (x1, y1) = (2, 0) and m = 2, the equation is ...
y -0 = 2(x -20
y = 2x -4
Write the slope-intercept form for linear equations. Substititute the y-intercept into the slope-intercept equation. Substitute both the x-intercept point and the y-intercept into the equation to solve for slope. Rewrite by substituting the values of and into the y-intercept form.

1. By the Law of Sines, you have:
SinA/a=SinB/b=SinC/c
2. You don't need the fraction SinC/c, so you can eliminate it. Then:
SinA/a=SinB/b
A=40°
a=19
B=m∠b
b=13
3. When you substitute this values into SinA/a=SinB/b, you obtain:
SinA/a=SinB/b
Sin(40°)/19=SinB/13
SinB=13xSin(40°)/19
m∠b=SinB^-1(13xSin(40°)/19)
m∠b=26.1°
Therefore, the answer is: 26.1 degrees.
