Question

please give me answer this question​

Answer 1

Step-by-step explanation:

let the two angles be "x" and "x + 18"

because one angle exceeds other by 18

their sum is equals to 180° since they are supplementary

x + x + 18 = 180

2x + 18 = 180

2x = 180 - 18

2x = 162

x = 162/2

x = 81

now....the two angles are...

x = 81

and

x + 18 = 81 + 18 = 99

hope it helps u.......

Answer 2

Answer:

let the angles be x and y (x > y)

condition:-1

x+y=180--- 1

condition:-2

x=y+18 ----- 2

subs x=y+8 in eq.1

y+18+y=180

2y=180 - 18

2y=162

y=162/2

y=81

subs y=81 in eq.2

x=81+18

x=99

Therefore the angles are 99° and 81°
