Question

the difference of two supplementary angle is 50 then find the anglea

Answer 1

Let the first angle be a

Second angle = 180 - a


According to question

First angle - Second angle = 50

=> a - (180-a) = 50

=> a - 180 + a = 50

=> 2a - 180 = 50

=> 2a = 230

=> a = 115


First angle = 115°

Second angle = 65°
