Answer 1

Answer:

since the angle BAC is an angle formed on a semi circle it will be 90° (1) and AB and AC are equal the angles opposite to it will also be equal(2) since the total angle of the triangle is 180°(angle sum property) from (1) and (2)

we get 90°+x+x=180°

180°-90°=2x

x=90°/2 =45°

therefore angle ABC is 45°
