Answer 1

Answer:

1. 35°
2. 60°

Step-by-step explanation:

In the given figure

<BAD = 30°(given )

<ABC = 55°(given)

In ∆ABC

<ACB = 90° (angle form on semicircle is 90 degree)

90° + 55° + <BAC = 180°(sum of angle of triangle is 180 degree)

<BAC = 35°

Now in ∆ADB

< ADB = 90° (angle form on semicircle is 90 degree)

Now

90° + 30° +<ABD = 180°(sum of angle of triangle is 180 degree)

<ABD = 60°
