Answer:
Explanation:
We know that:
- In an Isosceles triangle, two sides (Known as legs) are the same length.
- AB = 10 feet.
Let's solve this with the help of Pythagoras theorem.
- h² = 10² + 10²
- => h² = 100 + 100
- => h² = 200
- => √h² = √200
- => h = √200
- => h = √100 x 2
- => h = 10√2
Looking at the options, Option C is correct because 10√2 is equal to √200.
Hoped this helped.
