Answer:
Option A
2:1
Step-by-step explanation:
The radius of circle B is half of that of A meaning circle A's circumference is twice that of B
<span>EF = BC = a
ÐF is a right angle.
FD = CA = b
triangle
EF = BC = a
angle F is a right angle.
FD = CA = b
In triangle DEF,
By Pythagoras Theorem,
a2 + b2 = c2
the given
AB=c= a^2 + b^2 square root
Theorefore AB = DE
But by construction, BC = EF
and CA = FD
triangle ABC congruent to DEF (S.S.S)
