Can someone help me figure this out no guessing

laiz [17]

Your answer is x = 2.92 = 3.
To answer this question you need to use trigonometry, so the first step is to identify the hypotenuse, opposite, and adjacent.
Because the angle 73 is in the bottom corner next to the length x, we know that the length x is the adjacent. The length 10 is opposite the right angle so this must be the hypotenuse.
We know that cos(θ) = adjacent/hypotenuse, so we can substitute in what we know:
cos(θ) = adjacent/hypotenuse
cos(73) = x/10
Now we can rearrange for x:
cos(73) = x/10
× 10
cos(73) × 10 = x
Finally we just type this into the calculator and get the answer as 2.92 or 3.
I hope this helps!

Each wheel of gias bicycle is 24 inches in diameter gia rides her bike 1,884 feet to the nearest whole number how many times doe

cupoosta [38]

The wheel turned a total of 300 times in 1,884 feet.

Step-by-step explanation:

Step 1:

The wheels of the bicycle have a diameter of 24 inches. So the radius of the wheels is 12 inches.

To determine how many times the wheel turns we divide the distance traveled by the circumference of the wheels.

The circumference of a circle is given by multiplying 2π with the radius.

The circumference of the wheel $= 2(3.1415)(12) = 75.396.$

The circumference of the wheel is 75.396 inches.

Step 2:

Gia traveled 1,884 feet, we need to convert this into inches.

If 1 feet = 12 inches, 1,884 feet = 22,608 inches.

The number of times the wheel turned $\frac{22,608}{75.396} = 299.8567.$

Rounding this off, we get that the wheel turned a total of 300 times in 1,884 feet.

Express x in terms of the other variables in the diagram below:

GrogVix [38]

For the answer to the question above, just use similar triangles.
Here's the equations that I used.

t/h = (x + t) / r 
x + t = rt / h 
x = rt / h - t
I hope my answer helped you in your problem, Have a nice day
