Question

please ans the below given question

Answer 1

write the last line properly

Answer 2

let first angle be x

second angle be y


according to question .


< x+ < y = 80 ---------(1).



now ,

difference .



< x - < Y = 20 ---------(2) .


or

< y - < x =20 ----------(3) .





now ,

from equation 1 and 2 we get


<x = 50 °


< y = 30 °



therefore third angle is => 100 °




now , case second .



from equation 1 and 3



< x = 30° and <y = 50 °


and third angle is = 100 .




now , you got the two answer both are correct





hope it helps!!!
