Question

the larger of two supplementary angles exceeds the smaller by 18 degree find them​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Solution

✰Let the larger angle be =x

✰ and smaller angle = Y

According to the Question

⟹x+y= 180 ----(i )

⟹ x-y = 18 ----(ii )

⟹ x+y=18

⟹x= 180 -y------(iii )

✰ Putting the value of x in Eq---( ii)

⟹x-y= 18

180-y-y=18

180-2y=18

-2y= -162

$\implies \frac{ - 162}{ - 2}$

⟹ y= 81

✰putting the value of y in Eq ---(iii )

⟹ 180 -81

⟹x= 99
