Answer
its called x
Step-by-step explanation:
Since you did not include the figure with the circle to which you have to compare the equations, I am going to determine the center and radius of the circles represented by each of the equations.
From that, you choose that whose center is the same of your circle and the radius is the double.
The canonic equation of a circle is:
(x - a)² + (y - b)² = r²
Where a and b are the coordinates of the center (a,b) and r is the radius.
So, let's determine the center and the radius of all the equations given:
<span> A) (x – 4)² + (y – 6)² = 4
</span><span>
</span><span>
</span><span>Center (4,6),;radius = √4 = 2
</span><span>
</span><span>
</span><span>B) (x – 4)² + (y – 6)² = 16
</span><span>
</span><span>
</span><span>Center (4, 6); radius = √16 = 4
</span><span>
</span>
<span>C) (x – 6)² + (y – 4)² = 16
</span><span>
</span><span>
</span><span>Center = (6, 4); radius = √16 = 4
</span><span>
</span><span>
</span><span>D) (x – 6)² + (y – 4)² = 4
</span>
Center (6, 4); radius = √4 = 2
Answer:
48 , 132
Step-by-step explanation:
Let smaller angle = x
Larger angle = 3x - 12
x & (3x - 12) are supplementary
So, x + 3x - 12 = 180°
4x - 12 = 180
4x = 180 +12
4x = 192
x = 192/4
x = 48°
Larger angle = 3*48 - 12 = 144 - 12 = 132
Answer is D. 12. I just plugged it into an equation calculator. I use the website Symbolab.
