The legs of a right triangle are the sides that are connected to the 90 degree (right) angle. The remaining side is called the hypotenuse.
Another way to look at it is the two legs of a right triangle are the two shorter sides. The longest side is the hypotenuse.
1) 24
2) (-8)
Hope this helps
There exists a trigonometric identity which states that,
sin (A - B) = sin A cos B - cos A sin B
This is very similar to the given expression with A equal to 57° and B equal to 13°. The simplified form of the angle is,
sin (57° - 13°) = sin 44°
2r+7+2n+n2
Because I combined the ones with like terms.
