Question

11. A ranger in a lookout tower spots two fires on the campground below. Fire Als 75 meters east

Answer 1

Answer:

The fire hydrant = 9 meters west and south of the tower  = 58 m

Step-by-step explanation:

The coordinate as the origin includes the Fire A and Fire B

Given that

Fire A is 75 meters east and south of the tower is 40 meters

So, it is presented (75,-40)

And, the fire B is 37 west and south of the tower is 64 meters

So, it is presented (-37,-64)

Now at a point O (x,y) divides AB a line segment as A(x_1, y_1) and B(x_2, y_2)

So,

$x = \frac{n}{n+m} (x_2 - x_1) + x_1\\\\y = \frac{n}{n+m} (y_2 - y_1) + y_1$

Now it divides in three-fourth

So,

$x = \frac{n}{n+m} (x_2 - x_1) + x_1\\\\= \frac{3}{4} (-37-75) + 75\\\\= \frac{3}{4} (-112) + 75\\\\= -84 + 75\\\\= -9$

$y = \frac{n}{n+m} (y_2 - y_1) + x_1\\\\= \frac{3}{4} (-64-(-40)) + (-40)\\\\= \frac{3}{4} (-18) -40\\\\= -18-40\\\\= -58$

Hence, these two are to be considered
