First angle is of 28 degree and second angle is of 42 degree
sidmahesh2005:
can you give me steps
Firstly add 145+145=290 then subtract 290 from 360 as sum of all angles of quadrilateral is 360 after this u will take 2x and 3x as they are given in ratio now make equation of 2x+3x =70 , 5x=70 and we get value of x = 14 then 2x=28 and 3x=42
i can not understand

let other two angles be 2x and 3x then2x + 3x + 145 = 1805x = 180 - 145x = 35/5x = 7therefore angles are 14 degree (2x) and 21 degrees (3x)
