Answer:
Incident ray, the reflection ray and the normal to thereflection surface at the point of the incidence lie in the same plane
3/4. 4/8= 2/4. so 1/4+2/4=3/4
Answer:
fist bubble i am pretty sure
Step-by-step explanation:
3x+25=90
-25=-25
3x=65
x=26.6666666666666666666666
I hope this helps!
First we need to find the gradient of K
which is y1-y2/x1-x2
(-1,3) and (5,-2)
so it becomes 3-(-2)/-1-5
m=-5/6
when two lines are perpendicular their gradients multiply to make -1
that means the gradient of L has to be 6/5
we can substitute the point on L (5,-2) and the gradient of 6/5 into y=mx+c
-2 = (6/5) x 5 + c
c = -8
the equation of line L is y= 6x/5 -8
