Answer:
y=7
Step-by-step explanation:
The two given angels are congruent so they must be equal in measure.
Set them up equal and find y.
8y = 5y + 21, subtract 5y from both sides
8y -5y = 21, combine like terms
3y = 21, divide both sides by 3
y = 7
Answer:
The answer is C.
Step-by-step explanation:
m=y²-y¹/x²-x¹
m=(-12)-13/2-7
m=-25/-5
m=5
Answer:
<h2>The radius is 4 units long.</h2>
Step-by-step explanation:
The given equation is

This equation belongs to a circle, which center is at (0.5, 3.5) and its radius is 4.
You can deduct its elements, becase this equation of the circle is explicit, which means the constant term represents the square power of the radius. Solving that, we have

Therefore, the radius is 4 units long.
