Question

Solve for a side in right triangles (4.49 wasn’t right)

Answer 1

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

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.

`sine(40)=(x)/(7)`

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

`(7)sine(40)=x`

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
