Answer 2

Answer:

angle cab=45 degree

Step-by-step explanation:

given

aob is the diameter

angle c= 90 degree

ac=bc

to find

angle cab

proof

we know angles opposite to equal sides are equal

this implies , angle abc = angle bac

let angle abc=angle bac be x

in the triangle CAB

by angle sum propertu of triangle

x+x+90 = 180

2x+90=180

2x=180-90

2x=90

x=90/2

x=45 degree

hence angle abc=angle cab = 45 degree
