Question

Find the length of tangent draw circle radius 3 cm from the point distance 5 cm from center

Answer 1

Answer:

4 cm

Step-by-step explanation:

A right angle is formed at the circle by tangent and radius.

${3}^{2} + {x}^{2} = {5}^{2} \\ 9 + {x}^{2} = 25 \\ {x}^{2} = 16 \\ x = \sqrt{16} \\ x = 4$
