Answer:By definition, perpendicular line are two lines that intersect at right angles. In other words, the angle made by two lines should be 90°. Therefore, the use of distance formula does not help because it only tells you if the sides are equal. It does not tell you about the intercepted angle.
A technique that can help you to know if two straight lines are perpendicular is is you find their slopes. Let's say the slope of line 1 is m1 and the slope of line 2 is m2. If m1*m2 yields a product of -1, then the lines are perpendicular. This is because if m1 is the negative reciprocal of m2, the lines are perpendicular. But if m1=m2, the lines are parallel, meaning they don't intersect at all.
Therefore, the answer is: Find the slopes and show that their product is -1.

Answer:
210-20x=y
Step-by-step explanation:
150 is after 3 weeks of withdrawing 20 so $60
150+60=210 is the beginning amount
210-20x=y
I see your doing trinomials. It would be prime because nothing <span>adds to negative ten and multiplies to six.</span>
The answer to the question would be B which is 169.91 dollars
From the figure,
JHGF is a parallelogram.
From the properties of parallelogram,
∠ F = ∠ H (opposite angles are equal)
FG = JH (opposite sides are equal)
Also, note that FG || JH and JG is a transversal.
Therefore,
∠ FGJ = ∠ GJH (Alternate interior angles are equal)
Now, in Δ FGJ and Δ GJH,
FG = JH
∠ F = ∠ H and
∠ FGJ = ∠ GJH
Hence, the triangles are congruent by AAS Congruence Theorem.
