Answer 1

$\huge\fbox\red{Question}$

Two supplemtalay angles are in the radio

of 2:7, find the angle

$\huge\star{\green{\underline{\mathfrak{Answer:-}}}}$

Let the ratio be x

so first angle = 2x

and second angle = 7x

As the angles are supplementary .

so, 2x+7x=180°

9x=180 °

x= 20°

So first angle = 2×20° = 40°

and, second angle = 7×20° = 140°
