Answer: the height of the tree would be 10 feet.

Step-by-step explanation:

A tree and its shadow is proportional to Harry and his shadow. This means that

Height of the tree/height of the tree's shadow = Harry's height/height of his shadow

If Harry is 6 feet tall, his shadow is 9 feet and the tree's shadow is 15 feet long, then the height of the tree would be

6/9 = height of tree/15

height of tree = (6 × 15)/9 = 10 feet.

How do I show work for 5- (a-4) = 3 (a+2)

TEA [102]

Here is how I would show the work for this problem

5- (a-4) = 3 (a+2)
5-a+4 = 3*a+3*2
5-a+4 = 3a+6
-a+9 = 3a+6
-a+9+a = 3a+6+a
9 = 4a+6
9-6 = 4a+6-6
3 = 4a
4a = 3
4a/4 = 3/4
a = 3/4

So the solution is the fraction a = 3/4 (in decimal form 0.75)

Let me know if you have any questions or issues with any of the steps shown above. It's a lot to take in so feel free to ask about anything really.

Answer: 36.25°

Step-by-step explanation:

Use SOHCAHTOA (sin, cosine and tangent)

SOHCAHTOA:

SOH: Sin(θ) = Opposite / Hypotenuse

CAH: Cos(θ) = Adjacent / Hypotenuse

TOA: Tan(θ) = Opposite / Adjacent

When you have an angle that you want to solve, look at what information you're given. In this problem, we're give nthe sides that are opposite to and adjacent to the angle we want to solve. So, we use TAN.

And just as a note, θ this symbol is called theta, and it represents an angle.

TAN(θ) = Opposite / Adjacent = 11/15

Then, use the inverse of tan (you can find the button on a calculator). You can use the inverse of sine, cosine or tangent whenever you want to switch them from one side of the equation to the other.

TAN(θ) = $\frac{11}{15}$

θ = $tan^-1(\frac{11}{15} )$

Then, using a calculator, solve. The answer is about 36.25°
