Question

please answer me calculate the length of tangent from a point 15cm away from the centre of radius 9cm

Answer 1

length of tangent be x
${x}^{2} + {radius }^{2} = {15}^{2}$
${x}^{2} = {15}^{2} - {9}^{2}$
${x}^{2} = 225 - 81 \\ {x}^{2} = 144$
$x = \sqrt{144} \\ x = 12$
length of tangent equal to 12 cm
