Answer:

x = 65.4

The answer is 65.4 degrees.

Step-by-step explanation:

You can use either sine, cosine, or tangent to find the measure of angle x, but since the lengths of the adjacent leg and the hypotenuse are already given, cosine will be the easiest to use. The adjacent leg is 5 units long, and the hypotenuse is 12 units long.

Remember, cos(x) = adjacent / hypotenuse.

cos(x) = 5/12

cos^{-1}( ) both sides

cos^{-1}(cos(x)) = cos^{-1}(5/12)

Simplify (cos^{-1}(cos(x)) ⇒ x)

x = cos^{-1}(5/12)

Use calculator (make sure it is in degrees, not radians)

x = 65.37568165...

Round to the nearest tenth

x = 65.4

I hope this helps.

What is the slope and y-intercept of the line y=1/3x-7
Juli2301 [7.4K]

Answer:

1/3, -7

Step-by-step explanation:

Before answering this, I will need to assume that you actually meant

y = (1/3)x - 7.  Comparing this to y = mx + b, we see that the slope, m, is 1/3 and the y-intercept, b, is -7.

Felipe received a $40.00 gift card for a photo center. He used it to buy prints that cost 8 cents each. The remaining balance, B
Neko [114]
For better representation, I think the function is written as:

B(x) = 40.00 - 0.08x

This is much more comprehensive. The variable x represents the number of prints. So, if x=40 prints, we replace this to the x in the equation to find the balance B.

B = 40 - 0.08(40)
<em>B = $36.8</em>

On a map with a scale of 1 in. = 30 miles, the distance between Tarreytown and Hillville is 4 1/2 in. What is the actual distanc
Anit [1.1K]

The distance between the two towns is 75 miles.

<h3>What is the actual distance between the towns to the nearest mile?</h3>

We know that the scale of the map is 1 inch to 30 miles, this means that any measure that we get in inches in the map, should be multiplied by 30 to get the real measure in miles.

In this case, we know that in the map, the distance between the two towns is (4 + 1/2) inches.

Then the real distance in miles is given by:

d = (4 + 1/2)*30mi = 60mi + 15mi = 75mi

The distance between the two towns is 75 miles.
