Answer:
Pythagoras Theorem
Step-by-step explanation:
Like you rightly stated, in a right angled triangle. The phenomenon you mentioned is what us called Pythagoras theorem which proved to us that the square of the length of the hypotenuse of a right angled triangle, is equal to the square of the length of the opposite side to the angle in question, and also to the square of the length of the side adjacent to the same angle in question.
Essentially,
a² + b² = c², where c is the hypotenuse and a & b is the length of the two other sides
I'll do number 11 for you
Area of a sector can be found using
A = (πr²)C/360 where C is the measure of your central angle

A ≈ 23.56 m²
Oh, I guess rounded to the nearest tenth is 23.6
