Answer:

$x \approx 55.8$

Step-by-step explanation:

In order to solve this problem, one must use the trigonometric ratios. These ratios are the following,

$sin(\theta)=\frac{opposite}{hypotenuse}\\\\cos(\theta)= \frac{adjacent}{hypotenuse}\\\\tan(\theta)=\frac{opposite}{adjacent}$

Remember, each side is named relative to the angle, thus sides will attain different names depending on the angle which one sues to calculate with.

In this case, one is given the measure of the angle, and the measure of the side opposite to the angle. One is asked to find the measure of the side adjacent to the angle. Use the trigonometric ratio ( $tan$ ) to solve for the unknown. Substitute in the given values,

$tan(25)=\frac{26}{x}$

Manipulate the equation such that it is solved for the parameter(x),

$x=\frac{26}{tan(25)}$

Solve,

$x \approx 55.8$

I like to use ratios and cross multiply for problems like this. Take the part (1001) over the whole (1300), and that equals x percent of 100 percent.

1001/1300 = x/100
100100 = 1300x
x = 77

BaLLatris [955]

Answer:

The coordinates of point S are (6, 2).

Step-by-step explanation:

(x, y) where x is horizontal and y is vertical.

Point P's coordinates are (6, -4). Point S is 6 units above point P. This means we need to add 6 to point P's y value; -4.

-4 + 6 = 2

The y value is 2 for point S. The x value stays the same because we are not moving point S to the left or right of point P. The coordinates of point S are (6, 2).

Hope this helps,

John and Ariana bought school supplies, John spent $10.65 on 4 notebooks and 5 pens. Ariana spent $7.50 on 3 notebooks and 3 pen

timurjin [86]

Cost of 1 notebook is $ 1.85 and cost of 1 pen is $ 0.65

<h3><u>Solution:</u></h3>

Let "a" be the cost of 1 notebook

Let "b" be the cost of 1 pen

Given that John spent $10.65 on 4 notebooks and 5 pens

cost of 1 notebook x 4 + cost of 1 pen x 5 = 10.65

4a + 5b = 10.65 ------ eqn 1

Given that Ariana spent $7.50 on 3 notebooks and 3 pens

3a + 3b = 7.50 ----- eqn 2

Let us solve eqn 1 and eqn 2 to get the values of "a" and "b"

Multiply eqn 1 with 3

12a + 15b = 31.95 ---- eqn 3

Multiply eqn 2 with 4

12a + 12b = 30 ------ eqn 4

Subtract eqn 4 from eqn 3

12a + 15b = 31.95

12a + 12b = 30

(-) ---------------------

3b = 1.95

b = 0.65

Substitute b = 0.65 in eqn 1

4a + 5(0.65) = 10.65

4a = 7.4

a = 1.85

Thus cost of 1 notebook is $ 1.85 and cost of 1 pen is $ 0.65
