Answer:
10
Step-by-step explanation:
The radius is the magnitude of the complex number that is the difference between any point on the circle and the center point. A suitable calculator can tell you that magnitude:
║(8+7i) - (2-i)║ = √((8-2)² +(7-(-1))²) = √(36+64) = √100 = 10
Answer:
7/10
Step-by-step explanation:
10 marbles in a bag 7 of them are blue and the (10-7)=3 green

Answer:
a)
b) SSA does not constitute a proof. You need another fact.
Step-by-step explanation:

Angles opposite = sides are themselves equal.
<C = 50o
<J = 50o
But there is nothing that says x is 1/2 of <JAC
So it's unsolvable
Part B also has the same conclusion.
Answer:
x would equal x
