Use<span> your calculator to </span>find the value<span> of and the triangle to set up the ratio on the right. Solving the equation and rounding to the nearest tenth gives you . To </span>find<span> y, you can either </span>use<span> another </span>trigonometric function<span> (such as </span>cosine<span>) or you can </span>use <span>the Pythagorean Theorem.</span>
The arcs in the corners of the triangle signify that those two angles are equal. That means the triangle is isosceles, and the two sides opposite those angle are equal. In short,
... 4x +10 = 5x -25 . . . . . . sides opposite equal angles are equal
... 35 = x . . . . . . . . . . . . . . add 25-4x
A) opposite angle from sin theta 30 is cosine theta 60
b) and the opposite angle from cosine theta 60 is sin theta 30
