200/19.30 is the problem, the solution is 10.3626943 and if you round that it is 10.26. I hope this helps you!
We use the trigonometric identities in this problem.
=(sin(t)cos(4π)+sin(4π)cos(t))−(cos(t)cos(8π)−sin(t)sin(8π)) +<span>tan(t)+tan(5π)/1−tan(t)tan(5π)
=</span>sin(t)+0−cos(t)+0+ tan(t)1−0<span>=sin(t)−cos(t)+tan(t)
=</span>a−b+c
The slope of a horizontal line is always 0 because all its points have the same y-coordinate
Property being demonstrated here is corresponding angles.
Meaning 72 = x.
