Answer:

Step-by-step explanation:

The angle of incidence and reflection is 45°

The angle between them is 90°

they lie on the same plane, and angle of incidence = angle of reflection

the sum of all the angles is 180°

let angle of incidence and reflection be x

therefore,

90 + 2x = 180

x = 45°

What is an equation of the line that is perpendicular to y=-3/4x+6 and passes through the point (3,9)
goldenfox [79]

Answer:

y=\frac{4}{3}x+5

Step-by-step explanation:

The line y= -3/4+6 in the comments has slope -3/4. A perpendicular line will have the negative reciprocal of -3/4. It's 4/3.

To write the equation, substitute 4/3 and the point (3,9) into

y-y_1 = m(x-x_1)

y-9=\frac{4}{3}(x-3)\\\\y-9=\frac{4}{3}x -\frac{4*3}{3}\\\\y-9=\frac{4}{3}x-4\\\\y=\frac{4}{3}x+5
