Answer:
5√3 ft
Step-by-step explanation:
If the ladder is 10ft tall, then that represents the hypotenuse. If the foot of our ladder is 5ft away from the wall, that is a side length that we know. Using the Pythagorean Theorem, a²+b²=c², where a and b are side lengths of a right triangle, and c is the hypotenuse, we can solve for the missing side length:
a²+b²=c²
(5)²+b²=(10)²
25+b²=100
b²=75
b=√75
b=5√3
So the ladder will reach a height of 5√3 ft.

Oh, this is really easy!
Okay so the formula for the pythagorean theorem is a²+b²=c<span>²
So it doesnt really matter whats a or b
So take 21</span>²+15²=c<span>²
That ends up being 441+225=c</span><span>²
so next take 441+225 and that equals 666 then you have to find the square root so the square root of 666 is 25.81
S the answer is 25.81 </span>
