Step-by-step explanation:
We know that if the equation of the circle is (x-h)^2 + (y-k)^2 = r^2, it has a center of (h,k) and a radius of r.
Matching this up with the given equation, we get the center is (-5, 4) and the radius is 9.
Answer:
90º
Step-by-step explanation:
A triangle = 180º.
m<Z = 90º
So m<x + m<y = 180 - 90
That equals 90º

Answer:
Step-by-step explanation:
Let age of each twin be x
let age of sister be s
So we can write:
x + 4 = s
The product of the 3 siblings ages is 3482 more than sum. We can write:

This can be simplified as:

We replace s with "x + 4" and solve:

<u>Note:</u> To solve this cubic, we used technology
Thus, we can say the twins are 14 years old
