A walking path across a park is represented by the equation y= -3x - 6 . A new path will be built perpendicular to this path. Th
Romashka [77]

Answer:

The equation that represents the new path is y=(1/3)x+4

Step-by-step explanation:

step 1

Find the slope of the give line

we have

y=-3x-6

so

the slope m is equal to

m=-3

step 2

Find the slope of the perpendicular line to the given line

Remember that

If two lines are perpendicular, then their slopes are opposite reciprocal of each other

so

we have

m=-3 -----> slope of the given line

therefore

The slope of the perpendicular line is equal to

m=1/3

step 3

With m=1/3 and the point (-3,3) find the equation of the line

y-y1=m(x-x1)

substitute

y-3=(1/3)(x+3)

y=(1/3)x+1+3

y=(1/3)x+4 -----> equation that represent the new path

Please help. The topic is angles. Anything you know helps
Lorico [155]

Answer:

all of them except straight and reflex

Step-by-step explanation:

when angles are supplementary it means that they add up to 180

an acute angle is supplementary to an obtuse angle

an obtuse angle is supplementary to an acute angle

a right angle is supplementary to a right angle

but a reflex angle is over 180 so it's not supplementary to anything

and a straight angle is already 180 so it has no supplements either
