The value of x can be found using the sine function.
sin 30 = x/8
8 (sin 30) = x
4 = x

Answer:
y= -1*x +12
Step-by-step explanation:
x=4 is a function that always has the value 4 for the x-axis, no matter y variable, this a vertical function.
Perpendicular Lines are those with the following condition:
y=a*x+b (1)
y=c*x+d (2)
Where a and c are the respective slope
If These two lines are perpendicular, then
a=- 1/c
Using those principles we have that the slope for our needed line has to be -1, since the slope for the first line is 1 (the coefficient of x is 1, in the line x=4)
Lets use the given point (5,7) in the equation (2)
7=-1 * 5 + d
resulting d=12
so, our equation for the line is y= -1*x +12
Answer:
103.65 mph
Step-by-step explanation:
A bearing of 250 deg is 200 deg on the coordinate plane.
Find the x- and y-components of the speed vectors. Add them. Then find the magnitude of the resultant.
Hx = 110 cos 200° = -103.366
Hy = 110 sin 200° = -37.622
Ax = 0
Ay = 30
Hx + Ax = -103.366
Hy + Ay = -37.622 + 30 = -7.622
sqrt(-103.366^2 + -7.622^2) = 103.65
Answer: 103.65 mph
