Answer:
77.23°
Step-by-step explanation:
Given that,
A 135.8 foot wire is attached to the top of the tower.
The wire is attached to the ground 30 feet from the bottom of the tower.
It means,
If we consider a triangle such that hypotenuse is 135.8 foot and base is 30 feet, it means we can use the trigonometry as follows :

So, the angle the wire make with the ground is equal to 77.23°.
To find the value of x² + (2y) ÷(2w) +3z , first we substitute the values of w, x, y and z
5² + 2(8) ÷ 2(2) + 3(3)
To simplify this further, we have to apply the rule of BODMAS
(Applying the rule of BODMAS simply means when you have an equation, if its having bracket, you have to remove the bracket first, then you move to powers then you proceed to dividing then subtraction and then addition)
5² + 2(8) ÷ 2(2) + 3(3)
=25 +16 ÷ 4 +9
=25 + 4 +9
=38
Therefore the value of x² + (2y) ÷(2w) +3z is 38
It would be (9,5) or (9 9)
-9x(5-2x)Mutltiply the number outside of the parenthesis with the numbers inside the parenthesis
Final Answer: -45x+18x^2
This answer can no longer be simplified.
