Sin is equal to opposite over hypotenuse
With this we know that
Opposite = sqrt(12)
Hypotenuse = 4
To find adjacent we need to use the Pythagorean theorem
12 + adj^2 = 4^2
We then solve for adj
12 + adj^2 =16
adj^2 =4
adj =2
Now that we have opposite, adjacent, and hypotenuse, we can find cos and tan
Cos is equal to adj/hypotenuse
Cos = 2/4 = 1/2
Tan is equal to opp/adj
Tan = sqrt(12)/2

What is the slope of the line that passes through the points (1, 3) and (5, –2)?
Sergeu [11.5K]

m=-(5/4)

From left to right, (1,3) is first and then comes (5,-2). Always remember when finding slopes without equations, the rule is RISE over RUN, to the numerator and denominator, respectively.

The y value of the second coordinates becomes negative which is unlike the y value in the first coordinates, which means our slope is downward, meaning it has a negative sign in front.

In every slope, there’s a numerator, being the rise, and a denominator, being the run.

To find the rise, we must look at the y values. Starting at 3 going to -2 has a space of 5 units, making that our numerator.

To find the run, the first x value is 1 and the second is 5, making a space of 4, which is out denominator.

With these two numbers and the negative sign, we get -(5/4) as our slope.

Angi has 32 nickels and dimes. Their total value is $1.90. How many of each coin does she have?
Radda [10]

Answer:

6 dimes, 26 nickels

The number of nickels is N, and the number of dimes is D.

N + D = 32

5N + 10D = 190

N + 2D = 38

D = 6

N = 26

What is the area of this triangle?<br><br> _units²
MrRissso [65]

The area of the triangle is 4 units²

<h3>What is the area of a triangle?</h3>

The area of a triangle is the half the base multiplied with the height of that triangle

Area = 1/ 2 × b × h

From the figure given,

base = 7 - 3 = 4 units

height = 4 - 2 = 2 units

Area = 1/ 2 × 4 × 2

Area = 1/ 2 × 8

Area = 4 units²

Thus, the area of the triangle is 4 units²

The two way table shows the results of a survey that asked high school students whether they have a job.
Lynna [10]
(a) 50%
(b) 17%

Explanation:

(a)
No. of seniors = 54 + 46 = 100
Total No. = 66 + 34 + 54 + 46 = 200

% of seniors = 100/200 x 100% = 1/2 x 100% = 50%

(b)
No. of juniors that do not have a job = 34
Total No. = 66 + 34 + 54 + 46 = 200

% of juniors that do not have a job = 34/200 x 100% = 17/100 x 100% = 17%
