Remember the sign flips when you multiply or divide by a negative number.
1/4 because you just divde the numerator and the denominator by 12
Tanα=h/x
h=xtanα, we are told that x=6.5ft and α=74° so
h=6.5tan74 ft
h≈22.67 ft (to nearest hundredth of a foot)
12, 18 , 24, 30, 36, 42….
If the order matters it is a permutation.
