Answer:
y = 2x - 11
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - x + 1 ← is in slope- intercept form
with slope m = -
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= 2 , then
y = 2x + c ← is the partial equation
To find c substitute (8, 5) into the partial equation
5 = 16 + c ⇒ c = 5 - 16 = - 11
y = 2x - 11 ← equation of perpendicular line
Answer:
Step-by-step explanation:
In a right triangle only, the tangent of an angle is equal to its opposite side divided by its adjacent side. In this angle marked as is actually the same as the angle with point
.
Therefore, we can set up the following equation:
, where
is the distance from the coast.
Solving, we get:
