Answer:

47.7\ ft

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

In a right triangle the tangent of an angle is equal to divide the opposite side to the angle by the adjacent side to the angle

so

In this problem

tan(50\°)=\frac{BC}{AC}

The tall of the tree is BC

BC=ACtan(50\°)

AC=40\ ft

substitute

BC=40*tan(50\°)=47.7\ ft

Tan(angle) = opposite length/ adjacent length

Tan(50) = h/40
h = 40 x tan(50)
h = 47.67 or 47.7 feet

kykrilka [37]

Answer: 15

Step-by-step explanation:

I am assuming the equation is set up like this:

(x+9)/3 = 8

Multipy by 3 to both sides

x + 9 = 24

Subtract 9

x = 15
