I NEED HELP PLEASEE!! A helicopter flies on a bearing of 140° for 210 km then fliesdue
east for 175 km. How far east (to the nearest kilometre) has the helicopter travelled from its
starting point?

-1/2 +2

step-by-step explanation:

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b

y/x of point b= y/x of point a
