Question

1) find equation of straight line passing through (1,2) which makes an angle 15 degree with the line y = x+C ​

Answer 1

Answer:

this question ans is x=cy

Answer 2

Answer:

y-y1= m(x-x1) formula

Step-by-step explanation:

given passing through the point (1,2)

tita =15

we know that, m=tan tita

m=tan15 by expand it

we get.,m=tan(45-30)'

therefore, m=tan30

m=1/√3.

then, y-y1=m(x-x1)

y-2=1/√3(x-1)

by cross multiple √3,we get

√3y-2√3=x

but we want y=x+c,

√3y=x+2√3
