Answer:

Step-by-step explanation:
We know that we have a 9 foot long ladder resting upon a wall, with an unknown height, but the ladder is 4.5 feet away from the wall.
This can be represented as a triangle, where x is the unknown side.

We can use The Pythagorean Theorem to find the value of x. The theorem states that [tex]a^2+b^2=c^2[/tex], where a and b are the lengths of the legs and c is the length of the hypotenuse.
However, we already know the hypotenuse and one leg. Therefore we can substitute inside the equation to find the missing value.
[tex]a^2 + 4.5^2 = 9^2\\\\a^2 + 20.25 = 81\\\\a^2 = 60.75\\\\a \approx 7.79[/tex]

if x+y=2, calculate:
P=4x (x-3)+4y(y-3)+8xy
Answers
Answer:
Step-by-step explanation:
P = 4x(x - 3) + 4y(y - 3) + 8xy
= 4x² - 12x + 4y² - 12y + 8xy
= (4x² + 8xy + 4y²) - (12x + 12y)
= 4(x² + 2xy + y²) - 12(x + y)
= 4(x + y)² - 12(x + y)
x+y =2 ⇒ P = 4.2² - 12.2 = 16 - 24 = -8

find the values of x and z.
Answers
Answer:
x = 2
z = 93°
Step-by-step explanation:
set the top and bottom equations equal to each other...
5x + 77 = 9x + 69, solve for x...
subtract 69 and 5x from both sides...
8 = 4x
divide both sides by 4...
x = 2
substitute 2 for x in either equation...
5(2) + 77 = 87°
subtract 87 from 180...
180° - 87° = 93°
z = 93°
