Question

Is tangent to circle A at point G. If AG = 8 and GI = 15, determine the length of .

1) 17 units
2) 18.3 units
3) 15 units
4) 12.7 units

Answer 1

hope u want to know the length of AH.

it is 17 units

Explanation:

AGH is 90° (tangent )

AG is 8 units and GH is 15 units (Data)

so using Pythegorus theorem

AG² + GH² = AH²

gives √(8²+15²)

= 17 units
