${\huge{\fcolorbox{purple}{black}{Answer}}}$

According to the Question ,

First angle = x

Second angle = $\frac{4x}{5}$

as they are supplementry

so,

First Angle + Second Angle = 180°

x + 4x/5 = 180°

$\frac{5x+4x}{5}$= 180°

9x = 180° × 5

x = 20° × 5

x = 100°

so,

First angle = 100°

second angle = 80°
