Answer:
The sides of ∆ABC are 30 units, 40 units, and 60 units long.
The perimeter will be = units
Given is that ∆ABC and ∆XYZ are similar and the corresponding sides of ∆XYZ are 'r' times as long as the sides of ∆ABC.
So, perimeter of ∆XYZ will be : units.
----------------------------------------------------------------------------------------
The area of ∆ABC is n square units, so area of ∆XYZ will be :
=
= square units.
Answer:
(-21,-19)
Standard form
Step-by-step explanation:
We are given the equation of circle
General equation of circle:
Centre: (-g,-f)
Radius:
Compare the equation to find f, g and c from the equation
Centre: (-21,-19)
Radius (r)
Standard form of circle:
The centre of circle at the point (-21,-19) and its radius is .
The general form of the equation of a circle that has the same radius as the above circle is standard form.
