the width of the base of an isosceles triangle in inchesH Compute to six significant decimal places C For those whose geometry and trigonometry are a bit rusty, the center of an inscribed circle is at the point of intersection of the three angular bisectors. Input The input begins with a s...
the point where AC is tangent to the semicircle.According to the Pythagorean theorem, we immediately see that AC=17.The area of triangle ADC=DE×AC×0.5=AD×DC×0.5, so DE×AC=AD×DC.Let the radius of this semicircle be r, then DE=r.Then we have 8×15=17×r, so r=12017.A. ...
