Answer:
A⊥X
Since
A is perpendicular to Y
A⊥YAnd, X is parallel to Y
X || Y
That implies that A must be also perpendicular to X
A⊥X
Which means that they have the same slope (same inclination)

<h3>I'll teach you how to solve a-3/7 - 3-9/21</h3>
--------------------------------------------------------
a-3/7 - 3-9/21
Group like terms:
a - 3/7- 9/21- 3
Cancel 9/21 to 3/7:
a-3/7-3/7-3
Combine the fractions:
a- 6/7- 3
Convert element to fraction:
3*7/3 - 6/7
Since the denominators are equal combine the fractions:
-3*7-6/7
-3*7-6= -27
-27/7
Apply the fraction rule:
a- 27/7
Your Answer Is a - 27/7

Answer:
Step-by-step explanation:
The length of this triangle is 10 squares
and the width is 4 squares
The diagonals divide the rectangle into four triangles
These traingles are isoceles
Each two triangles facing each others are identical
<B = 90 degree
B = alpha + Beta
Let Beta be the angle next alpha
The segment that is crossing Beta is its bisector since it perpendicular to the diagonals wich means that:
Beta = 2x
Then B = alpha + 2x
90 = alpha +2x
90-alpha = 2x
x = (90-alpha)/2
As the independant variable increases, the dependant variable increases at a constant rate creating a linear relationship.
