Question

find the value of y.
Angle 1=3y-6

Answer 1

I think you need to include a diagram...

Answer 2

Here, m1, which is the slope of the first line = 2 and m2, which is the slope of the second line = -3

Substituting in the above formula,

θ = tan⁻¹|(-3-2)/(1+6)|

==> θ = tan⁻¹(5/7)

Answer 3

that is the picture for the equation
