X = 25 +4*(90 -x) . . . . . x is 25 more than 4 times its complement
x = 385 -4x . . . . . . . . . eliminate parentheses
5x = 385 . . . . . . . . . . . .add 4x
x = 77 . . . . . . . . . . . . . . divide by 5
The measue of angle x is 77°.
Answer:
The answer is correct x =6.8, if she made an error, it might have been the steps she took.
Step-by-step explanation:
5.4 + x = 12.2
subtract 5.4 from both sides to put x terms on the left hand side, numerical number terms on the right hand side
5.4 - 5.4 + x = 12.2 - 5.4
x = 6.8
