Answer:
a =
Step-by-step explanation:
To find the value of a, find the Slope of both the equations.
For lines to be perpendicular to each other
For line 1:
2x + 3y − 6 = 0 represent the line in y=mx +c form
3y = -2x + 6
y = +
y = + 2
=
For line 2:
ax - 3y = 5
ax = 5 + 3y
ax - 5 = 3y
y =
=
Apply the condition of perpendicularity:
*
= - 1
a =
She has distributed the bracket incorrectly
(64 + 5) - 0.2(- 20 + 10)
= (69) - 0.2 (- 10)
=34.5 + 2
= 36.5
You can use the cosine rule for this - you might have to change some of the letters around for it to make sense though. Hope this helps!
