I cant really see the numbers (3-4) which do u need
First let us determine what <ABD is: 180º- 90º - 2nº = 90-2nº (the square represents a 90º angle
Then find <DCB: 180º - 90º - nº = 90-nº
Angle <ACB doesn't change: it is 90-n
but, <ABD is only part of <ABC: if we add <ABD with <DBC then we get 90-2n+n = 90-n
Definition of an isoceles triangle: It has two sides that are congruent or has two angles that are congruent.
Because both <ABC and <ACB equal 90-n the triangle ABC is an isoceles triangle.
Hope this Helps, and May the Force Be With You!

Answer:
A) parallel
It has the same slope.
y-intercept is 6.
So,
m = -5
b = + 6
y = -5x + 6
B) perpendicular
It has a negative reciprocal of the slope.
-5 = 1/5
y-intercept is 6
m = 1/5
b = + 6
y = 1/5x + 6
