(12 points and brainliest for best)
you may have seen the star betelgeuse (beetle juice) in the
night sky. it is a red giant star, which has a radius of 821.3
million kilometers. by comparison, our sun has a radius of 0.5
million kilometers.
suppose the circle shown represents our sun. how big would
the model of betelgeuse be if you drew it to scale?

step-by-step explanation:

(x) - (y) = (1 + 4i)

perimeter of the base times height

step-by-step explanation:

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²
