Answer:
B
Step-by-step explanation:
A rhombus is divided into four congruent triangles. The two given angles are complementary, meaning they add up to 90 degrees. Set up an equation:
Take out the parentheses
Combine like terms
Add 25 to both sides so as to isolate the variable
Divide both sides by 5
Answer:
Center:
Radius:
Step-by-step explanation:
It is necessary to remember that the Equation of the circle in Center-radius form, is:
Where the center of the circle is at the point (h, k) and the radius is "r".
Then, given the following equation of the circle:
We can notice that it is written in Center-radius form. Then we can identify that:
Therefore the center is:
And the radius is:
