Answer:

540°

Step-by-step explanation:

If a triangle (3 sides) has 180 degrees then we can figure out the degrees in a pentagon.

180° + 360° = 540°

How? The "top" part could be seen as a triangle (180 degrees), and we know that a quadrilateral's angles add up to 360 degrees, so when we add them together we get out answer!

Write the equation in standard form for the circle with center (-5, 3) and radius 10.
Vladimir [108]

Answer:

x² + y² +10x -6y - 69 = 0

Step-by-step explanation:

We need to write the standard equation of circle with , centre (-5,3) and radius 10 unit . The Standard equation of the circle ⭕ is ,

=> ( x - (-5))² + (y -3)² = r²

=> ( x +5)² + (y-3)² = 10²

=> x² + 25 + 10x + y² +9-6y = 100

=> x² + y² +10x -6y + 31 = 100

=> x² + y² +10x -6y - 69 = 0

<h3>• Hence the equation of the circle is x² + y² +10x -6y - 69 = 0.</h3>
