Question

In the figure find ZABC
(a) 90° (b) 45°
(c) 15°
(d) 30°
​

Answer 1

Answer:

The answer is 45

Step-by-step explanation:

Angle between the semicircle is 90

As Of and OB are radii

/_ACB =/_ABC =45

Answer 2

Answer:

< ABC = 45°

Step-by-step explanation:

<BAC = 90° (Angle in the semicircle is of 90°)

Since, AB = AC

So, <ABC = <ACB (Angles opposite to equal sides of triangle are equal)

By angle sum property:

<ABC + <BAC + <ACB = 180°

<ABC + <ACB + 90° = 180°

<ABC + <ABC = 180° - 90°( <ABC = <ACB)

2<ABC = 90°

<ABC = 90°/2

<ABC = 45°
