Question

The angles of a quadrilateral all in ap whose cd is 10 find its angles​

Answer 1

Answer:

Measure of angles are 75 , 85 , 95 , 105

Step-by-step explanation:

let the smallest angle of quadrilateral be 'a"

angles are in ap with common difference 10

angles = a , a + 10 , a+20 , a+30

a+a+10+a+20+a+30 = 360. ( measure of all angles of quadrilateral )

4a + 60 = 360

4a = 360 - 60

4a = 300

• a = 75
• a+10 = 85
• a+20 = 95
• a+30 = 105
