Answer:
3.1
4.2
5.2
42
Step-by-step explanation: Just copy the other cone and find half of the diameter to find the radius the cones are congruent.
A=3.1
B=4.2
C=5.2
D=42
Step-by-step explanation:
Was right on edge
y=1/2x
y=(6/5)x
f(x) =
substitude the y value into y in the first equation
-8-(12x-50)=30
-8-12x+50=30
you see it?
then solve
-8+50-30=12x
you got the value = 12x
then you divide with 12
finally you get x
