Answer:
x = 9
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
x² + x² = (9[tex]\sqrt{2}[/tex] )²
2x² = 162 ( divide both sides by 2 )
x² = 81 ( take the square root of both sides )
x = [tex]\sqrt{81}[/tex] = 9

Part b: Find the length of the sidewalk. The walk is the hypotenuse of a right 30-60-90 triangle with horizontal side 2√3. Using the 30° angle as the reference angle, we get the following from the definition of the cosine function:
cos 30° = adj / hyp, or:
√3 2√3
------- = --------
2 hyp
This simplifies to
1 2
-------- = -------
2 hyp
Cross multiplying results in: hyp = 4. The sidewalk length is 4 miles.
a. The width of the park can be found using the sine function, the now-known hypotenuse and the 30° angle:
1 opposite side
sin 30 degrees = ----- = ------------------------- or 2(opp side) = 4.
2 4
Then the opp side, which is the width of the park, is 2.

If steak costs $12.55 per pound, what will be the total cost of 0.6 pounds of steak?\
Answers
Answer:
Solve for X; whereas lb=pound, $=cost
1lb = $12.55
0.6lb = $X; therefore 6/10 lb = $X
Rewrite:
$12.55/1 lb = $X/6/10 lb; therefore $12.55/1 lb = 10/6(X); 10X=$12.55(6); 10X=$75.30; X=$75.30/10
X=$7.53 for .6 lbs.

Leticia bought a new tablet for $425. She had to pay a sales tax of 8%.
What was the amount of sales tax she paid on the tablet? Sales Tax: $
What was the total cost after sales tax that Leticia paid for the tablet? Total: $
Answers
Total: $459
Step to solve:
To find sale tax you would need to multiple 425, the cost of the tablet by 8% or 0.08 in decimal form to get the answer 34.
To find the total add the sale tax, 34, and the cost of the tablet, 425, to get the total, 459 dollars.

The path of a projectile launched from a 26-ft-tall tower is modeled by the equation y = −16t2 + 64t + 26. What is the maximum height, in feet, reached by the projectile?
Answers
Answer:
The maximum height of the projectile is 90 ft
Step-by-step explanation:
Here, we want to get the maximum height reached by the projectile
The answer here will be the y-coordinate value of the vertex form of the given equation
so firstly, we have to write the equation in the vertex form
We have this as;
y = -16t^2 + 64t + 26
That will be;
y = a(x-h)^2 + k
y = -16(x-2)^2 + 90
where the vertex of the equation is;
(-h,k)
K
in this case is 90 and thus, that is the maximum height of the projectile

(a and b are the lines that form a right angle and c is the line that doesn’t)
a = 16

Answer:
16.5
Step-by-step explanation:
a² + b² = c²
x² + 16² = 23²
x² + 256 = 529
x² = 273
x = √(273)
x = 16.52271164...

Answers
Answer:
20.78 feets
Step-by-step explanation:
Based on the solution diagram attached below :
The height at which the step ladder meets the house can be obtained thus :
Using trigonometry :
Sin θ = opposite / hypotenus
Sin θ = h / 24
Sin 60 = h / 24
0.8660254 = h/24
Height, h = 0.8660254 * 24
Height, h = 20.78 feets
