supplementary angles = 180 degree
let no. = 7x and 8x
7 x+ 8x=180
15x =180
x=180/ 15
x=12
angles = 7*12=84
8*12=96

First anlge = 7x
Second angle = 8x
Now,
supplementary angles = 180°
So,
7x + 8x = 180°
15x = 180
x = 180 / 15
x = 12
So, the first angle = 7x
= 7× 12
= 84°
And, the second angle = 8x
= 8×12
= 96°
Second angle = 8x
Now,
supplementary angles = 180°
So,
7x + 8x = 180°
15x = 180
x = 180 / 15
x = 12
So, the first angle = 7x
= 7× 12
= 84°
And, the second angle = 8x
= 8×12
= 96°
