The answer is 18.31 because 55/4 is 13.75
Then 129 degrees minus 90 degrees is 39 degrees so
1+tan^2=sec^2
so, given expression=
(using sin/cos=tan and tan*cot=1)
hence proved
Answer: $400
Step-by-step explanation:
So first you set it up in a equation. You put the amount she put in the bank over x (the x represents her full salary) which equals the percent she already spent over her full salary. That would be 120/x=30/100 you would then cross-multiply to get 12,000 = 30x. you then divide 30 from both sides to get x =400.
