Mathematics
1 answer:
RUDIKE [14]2 years ago
8 0

31) x = 25 degrees

Equation: (2x+15) + x + 90 = 180 degrees

--> 3x+105 = 180

-------> 3x = 75

-------------> x = 25 degrees

32) x = 17 degrees

Equation: (x+52) + (3x+21) + 39 = 180 degrees

--> 4x+112 = 180

-------> 4x = 68

-------------> x = 17 degrees

The equation of a circle is x2+y2−12x+6y+20=0 .
Rufina [12.5K]

Answer:

The radius is r=5 units

Step-by-step explanation:

we know that

The equation of the circle in standard form is equal to

(x-h)^{2}+(y-k)^{2}=r^{2}

where

(h,k) is the center and r is the radius

we have

x^{2}+y^{2}-12x+6y+20=0

Convert to standard form

Group terms that contain the same variable, and move the constant to the opposite side of the equation

(x^{2}-12x)+(y^{2}+6y)=-20

Complete the square twice. Remember to balance the equation by adding the same constants to each side

(x^{2}-12x+36)+(y^{2}+6y+9)=-20+36+9

(x^{2}-12x+36)+(y^{2}+6y+9)=25

Rewrite as perfect squares

(x-6)^{2}+(y+3)^{2}=5^{2}

therefore

The center is the point (6,-3) and the radius is r=5 units
