Answer:
51/9 or 5 2/3
Step-by-step explanation:
First, multiply both sides by b-1 using the distributive property.
6/(b-1)=9/7
6=9(b-1)/7
6=(9b-9)/7 Multiply both sides by 7.
42 = 9b-9 Add 9 to both sides.
51 = 9b Divide both sides by 9.
b = 51/9 or 5 2/3
Draw a right triangle ABC with, the point where the top touches the ground and one leg, BC, the stump, measuring 14 ft.
The height of the tree = hypotenuse + stump BC (14 ft)
If the ∠ of inclination = 43°, then ∠ CAB = 37°
Now let's apply the law of sine:
sin 37°/14 = sin 43°/AB →and AB = 14.sin 43°/sin 37° = 15.86
Hypotenise² = AB² + CB²
Hypotenuse² = 15.85² + 14² = 447.22 → and Hypotenuse = 21.14 ft
Tree Height = hypotenuse + stump = 21.14 + 14 ≈ 35 ft
You add them all up and you divide them from 5 and that's 49097/5 and that equals 9819 and 2/5 and that in decimal form is $9819.40.
