Answer:
The second one down
Step-by-step explanation:
The 26 ft ladder is the hypotenuse of the right triangle
24 feet is the vertical leg
They each have $42 because 7 times 6 is 42 and combined they have $84 because 42 + 42=84.
The fraction 8/21 cannot be simplified because the numerator and denominator don't have a common factor except 1.
Pythagorean Theorem
a² + b² = c²
c = 13
a = 4
(Missing side) = b
4² + b² = 13²
16 + b² = 169
16 - 16
169 - 16 = 153
Square Root of 153 = 12.369
b = 12.369
The missing side is 12.369 (rounded to 12 as a whole number)
