Answer:

see explanation

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

(x - 6)² + (y + 1)² = 40 ← is the equation of a circle in standard form

centre = (6, - 1) and r = \sqrt{40} = 2\sqrt{10}

Help me with a math question plz
Kruka [31]

Answer:

x = 80

Step-by-step explanation:

Thank you for the clear diagram. We don't always get them.

Argument

There are two kinds of angles associated with a triangle

  1. Interior angles
  2. Exterior angles

You have both kinds in this question. The interior angles are the ones that make up the triangle itself. The ones you are concerned about are x and 38°.

The other kind is formed by extending one of the sides. In this question, the value of the exterior angle is 118°.

Rule

The two interior angles NOT connected to the given exterior angle are equal (when added) to the exterior angle.

In plain English what that means is

x + 38 = 118

Solution

x + 38 = 118                      Subtract 38 from both sides.

x + 38 - 38 = 118 - 38      

x = 80

So x = 80

How do you construct a regular polygon inside a circle?
Tresset [83]

You could use a ruler, think about how you want the polygon inside of the circle or how you want the circle to surround the polygon. When you use a ruler, make sure your co-ordinates inside of the circle are correct though before drawing the line.

I hope this info helps! :3
