Question

need it urgently.....plse help me to understand the question and plsee solve it

Answer 1

it would help to know the slope (tangent) of the given degrees

Answer 2

given a slope (m) and a point (a,b); a line can be constructed as:

y = m(x-a) + b

Answer 3

assuming we can find m, how would you set up the 4 lines

Answer 4

srry 'i don't know

Answer 5

i posted the instructions, the format, the setup .... you will have to tell me what you do not understand about it

Answer 6

okay

Answer 7

u wrote set up 4 lines..what does that mean

Answer 8

the question is asking you for 4 lines ....given a slope (m) and a point (a,b); a line can be constructed as:

y = m(x-a) + b

assuming we can determine the slope (m) later, can you set up the 4 lines that the question is asking for?

Answer 9

but if we want to set up 4 line, we need to put a and b value in y = m(x-a)+b

Answer 10

correct, can you give me the points that they want? one is directly stated, and the other is infered.

Answer 11

a=0 and b= 2

Answer 12

second one is a=0, b=0
third one is a=0, b=2

Answer 13

(0,2) is one of them

y = mx + 2 will take care of 2 lines thru (0,2)

-----------------------------------------

the point that is 2 below the origin is: (0,-2)

y = mx - 2 will take care of 2 lines thru (0,-2)

Answer 14

itll look like this

Answer 15

okay

Answer 16

so, we need to determine the slope that will work, do you have an idea on how we could determine those slopes?

Answer 17

hmm.no

Answer 18

the give us a measures of angles in degrees. to me this means that we can use trigonometry to determine the slope of the lines:

m = y/x

tan(angle) = y/x

Answer 19

they give us 60 and 120 degrees; m1=tan(60) and m2 = tan(120)

y1 = tan(60)x + 2
y2 = tan(120)x + 2
y3 = tan(60)x - 2
y4 = tan(120)x - 2

Answer 20

okay

Answer 21

just as an aside:

tan(60) = sqrt(3)
tan(120) = -sqrt(3)

Answer 22

so what after this

Answer 23

@amistre64
what to do next

Answer 24

well, seeing how we have "found" the 4 lines .... or at least equations for them; unless there is a picture to choose from id say its done

Answer 25

it means only in this question we have to find y1, y2, y3 and y4
that's it

Answer 26

ok, since we found them ... there is nothing left to do with the question :)

Answer 27

k

Answer 28

@amistre64
thank u

Answer 29

good luck
