Answer:
is equation of BC
Step-by-step explanation:
Given that AB and BC form a right angled triangle at point B.
i.e. BC is perpendicular to AB
Line AB contains two points (-3,-1) and (4,4)
Slope of AB =
Slope of BC would be -1/slope of AB since AB and BC are perpendicular
Slope of BC =\frac{-7}{5}
Also we got a point on BC as B.
Use point slope formula
Based on the definition of the diagonals of a rhombus, m∠AED = 90°.
<h3>What are the Diagonals of a Rhombus?</h3>
A rhombus has two diagonals that bisect each other at right angles, that is they are perpendicular to each other.
Angle 90 is formed at the intersection of the two diagonals of a rhombus.
In rhombus ABCD, ∠AED is formed at the intersection of the diagonals of the rhombus.
Therefore, based on the definition of the diagonals of a rhombus, m∠AED = 90°.
