If bd = 0.6 in. and ab = 0.8 in., calculate the length of line segment da . circle d with tangent line segment ac touching the circle's edge at point b; radius db; line segment ad
we know that if AC is a tangent line segment then AC is perpendicular to segment BD
therefore in the right triangle ABD applying the Pythagorean Theorem AD²=BD²+AB² BD=0.6 in AB=0.8 in AD²=0.6²+0.8²----> AD²=0.36+0.64-----> AD²=1 AD=1 in
the answer is the length of line segment DA is 1 in
