IM GIVING 20 POINTS. help me please. it would be very helpful

14.14 ft

Step-by-step explanation:

In an isosceles triangle, the altitude and median is same. So the height divides the base AB equally such that AD = DB = 10, if the height is CD. So using Pythagoras theorem, we can find the hypotenuse AC in triangle ADC.

h² = b² + a²

AC² = AD² + CD²

AC² = 10² + 10²

AC² = 100 + 100

AC² = 200

AC = √200

AC ≈ 14.14 ft

Hope this answer helps you!!

Please mark me as the brainliest!!

the answer is simply just 6n add the two together as they have an n
