Find an equation of the vertical line that passes through the point (4,-2).

x = 4 is the equation

The equation of a vertical line , parallel to the y-axis is

x = c where c is the value of the x-coordinate the line passes through

the line passes through (4 , - 2)

Thus equation is x = 4

its 50 miles away from the starting point

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
