Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

<cdb = 45°

<adb = 60°

Step-by-step explanation:

It is given that <dab = 75° and <dbc = 60°

Since ABCD is a parallelogram, opposit angles are equal

<dab = <bcd and <adc = <abc

Therefore <dab + <bcd = 75 + 75 = 150°

To find <adb

<adb = <dbc (alternate interior angle)

therefore <adb = 60°

To find <cdb

<adc + <abc = 360 - 150 = 210

<adc = 105 and <abc = 105

<abc = <abd + <cbd

<abd = 105 - 60 = 45°

<abd = <cdb = 45° (alternate interior angle)

<cdb = 45°
