Answer:
4.50 or 4.5. The only reason you got it wrong was because you didn't round to the nearest hundredth. 4.499 rounds up to 4.50
Step-by-step explanation:
Hopefully you know what the sine and cosine functions are...
So you gotta use the sine function for this equation since you are given the hypotenuse and B.
[tex]sine(40)=\frac{x}{7}[/tex]
We put the degree measure next to sine because there can only be one unknown
So we can solve from here by multiplying both sides by 7
[tex](7)sine(40)=x[/tex]
Now put your calculator in the degree mode and insert this equation into it.
You get 4.499 rounded to the nearest hundredth is 4.50
