Question

I need the answer pls​

Answer 1

Answer:

radius =1/2(ED)=10cm=OA.(RADIUS)

AC=1/2(AB)=8

join OA.

in triangle AOC,

OC^2+AC^2=OA^2

OC^2=10^2-8^2

OC^2=100-64=36

OC=6cm

in triangle ACE,

AE^2=AC^2+CE^2

AE^2=8^2+(OC+OE)^2

AE^2=64+(6+10)^2

AE^2=64+256=320

AE=root320=8root5cm

therefore,OC=6cm and AE=8root5cm.
