Question

Pls answer this question fastly it's urgent ​

Answer 1

Answer:

fist of all AB can't be diameter

Then too, AB is a diameter, the it's opposite angle will always be 90degree.

Than by angle sum property of triangle, angle B=45degree.

Now by Pythagoras theorem, AB =

14.4cm

Answer 2

Step-by-step explanation:

ab is diameter of circle

then angle C=90[angle of semi circle]

in triangle abc

45+90+b=180

b=45

AC=BC[side opposite angle

ac=10

triangle abc is a right angle triangle

AB2=AC2+BC2

AB2=100+100

AB=√200

AB=14.15
