Answer:
b=130°
Step-by-step explanation:
The relationship between these two angles is about the fact that they are supplementary
i.e their sum is 180°
Let x=small circle
2x = bigger circle
πx^2 + π(2x)^2 = 80π
x^2 + 4x^2 = 80
5x^2 = 80
x^2 = 16
x = +/- 4
but we need the positive one because there's no negative measurement so
the answers are:
4m and 8m
Vertex: 0,4.92
focus: 0,4.8575
axis of symmetry: x = 0
directrix: y = 4.9825
Answer:
Line
intersects line 
Step-by-step explanation:
We are given that
Subtract one equation from other then we get
Substitute the value of x in first equation then we get
Hence, the solution 
is the intersection point of two line equations .
Answer:Line intersects line
