Distribute this one
so lets start with the x variable
x*x^3
x*5x^2
x*19x
then lets go to 4
4*x^3
4*5x^2
4*19x
so the WHOLE answer is
x^4+4x^3+3x^3+20x^2+19x^2+76x

From the diagram below, if the tree is 34 ft. tall, and the angle of elevation from point B to the top of the tree is 26 °, find

lana66690 [7]

Given the height of the tree and the angle of elevation from point B, the distance between the tree is from point B is approximately 70ft.

<h3>What is the distance between the tree and point B?</h3>

Given the data in the question;

Height of tree opposite angle of elevation = 34ft
Angle of elevation θ = 26°
Distance between tree and point B| Adjacent = ?

Since the scenario form a right angle triangle, we use trig ratio.

tanθ = Opposite / Adjacent

tan( 26° ) = 34ft / x

We solve for x
x = 34ft / tan( 26° )

x = 34ft / 0.4877

x = 70ft

Given the height of the tree and the angle of elevation from point B, the distance between the tree is from point B is approximately 70ft.

From corresponding angles theorem, we can see the 2 angles are equal.

16x+13=18x-1

2x=14

x=7

Done!

Any questions just leave them in the comments and I will answer.

Answer: The answer is $698.00

Step-by-step explanation: For example, if you are receiving SSI and make $200 per month in earned income, the deduction will be made like this: $200 – 20 = $180 – 65 = $115.00/2 = $57.50 Meaning $57.50 would be deducted from the maximum SSI payment of $698.00 month.
