Step-by-step explanation:
Tip: When finding the circumference of a circle, just multiply the radius by 2!
Hope I get my brainliest even tho I couldn't get all of it!
Since a line =180 degrees you could set it up as (180-85) and you would get <u><em>95.
Hope this helps!!!</em></u>
Answer:
b = 6
Step-by-step explanation:
You probably already know the general equation from the my last couple of answer.
In this question, we have:
a=8
b= ?
c= -10 , c is the value of the foci
surprisingly, you can solve the value for a, b, and c using the same equation as the Pythagorean theorem.
c² = a² + b²
we need to solve for b so lets rearrange the equation.
b² = c² - a²
b = ±√(c² - a²)
b = ±√((-10)² - (8)²)
b = ±√((-10)² - (8)²)
b = ±√(100 - 64)
b = ±√(36)
b = ±6
b = 6
