Marco's equation is correct.  Cosine is an even function, which means that for every x, f(-x) = f(x).  In other words, you get the same answer for a negative value that you would for its corresponding positive value.

Can anyone help me with question number 3
ira [324]
The answer is: There are 595 calories in a banana split 

To find this we first need to set up our equation: 

80= \frac{1}{7}x-5, where x= calories in a banana split


85= \frac{1}{7}x----------------Add 5 to both sides

595=x-------------------Multiply 7 to both sides to get rid of the fraction

So, there are 595 calories in a banana split

Hope this helps! :)

The measures of a triangle are in the ratio 2:3:5. what are the measures of the angles?
xxTIMURxx [149]

9514 1404 393

Answer:

  36°, 54°, 90°

Step-by-step explanation:

We have to assume that the given measures are <em>angle</em> ratios, not <em>side</em> ratios. Sides in the ratios 2:3:5 will not form a triangle.

For some multiplier x, the angle values will total 180°.

  2x +3x +5x = 180

  x = 180/(2+3+5) = 18

Then the angle measures are ...

  2x° = 2·18° = 36°

  3x° = 3·18° = 54°

  5x° = 5·18° = 90°

The angle measures are 36°, 54°, and 90°.
