Question
Two tangents are drawn from an external point to a
circle with radius 8 cm, and the distance between the external point and the center of the circle is 17 cm. What is the length of each tangent?ÂSolution
The length of the tangent from an external point to a circle is given by √(d² - r²), where d is the distance from the external point to the center, and r is the radius. Substituting the values, √(17² - 8²) = √(289 - 64) = √225 = 15 cm. Correct answer: d) 15 cm
