The general equation of circles is (x-h)^2 + (y-k)^2 = r^2 where (h,k) is the center. 
1. 2x^2+2y^2=72 =x^2+y^2=36  c: (0,0); r = 6
2. (x-3)^2+(y-1)^2=4 : c: (3,1); r = 2
3. (x-5)^2+(y+2)^2=49;  c: (5,-2); r = 7
4. (y-4)^2+(x-10)^2=64:  c: (4,10); r = 8
5.(x^2-6x+9)+(y^2+8y+16)=1:  c: (3,-4); r = 1
6. x^2+12x+y^2-8y=-27 =<span>x^2+12x + 36+y^2-8y+16=-27+36+16=25:
 c( -6,4); r = 5</span>

The angles measures x and 4x are complementary angles. Which is the value of x?
Hitman42 [59]

<u>Answer:</u>

The angles measures x and 4x are complementary angles. The value of x is 36 degrees

<u>Solution:</u>

Given, two angles are x and 4x

We have to find the value of above given x  

We are also given that, given two angles are complementary angles for each other

So, we know that, <em>sum of any two complementary angles will always be equal to 180 degrees </em> 

Then, in the problem given,

x+4 x=180 \rightarrow 5 x=180 \rightarrow x=\frac{180}{5} \rightarrow x=36

Hence the angles measures x and 4x are complementary angles. The value of x is 36 degrees
