find in short way.... ​

Answer 1

Answer:

x= 1083.89

Step-by-step explanation:

(23.1)2 + (48.6)2-(39.8)2 = ? + 1147.69

(23.1)2 + (48.6)2-(39.8)2 = x+ 1147.69

2  ( (23.1) + (48.6) -(39.8)  ) = x+ 1147.69

2 ( 23.1+48.6-39.8)=x+1147.69

2 ( 23.1+8.8 )=x+1147.69

2 ( 31.9  )=x+1147.69

63.8=x+1147.69

x=63.8 - 1147.69

x= 1083.89
