How do I solve a given right triangle to find Cos, Sin, and Tan. How do I solve for a missing adjacent side? (For Example: Imagi

Sphinxa [80]

The steps to find cos, sin, and tan and missing adjacent side of a given right angle triangle is explained.

<u>Solution:</u>

Given, a right triangle with A, B, and C.

Opposite side = 70 inches

Hypotenuse = 12 feet = 12 $\times$ 12 inches = 144 inches

Adjacent side = "x" inches.

We are not given angle, so we have to use the hypotenuse theorem

Hypotenuse theorem means square of the length of the hypotenuse is equal to the sum of squares of the lengths of other two sides of the right-angled triangle.

$\text { hypotenuse }^{2}=(\text { opposite side })^{2}+(\text { adjacent side })^{2}$

Substituting the values we get,

$\begin{array}{l}{\rightarrow 144^{2}=70^{2}+x^{2}} \\\\ {\rightarrow x^{2}=20736-4900} \\\\ {\rightarrow x^{2}=15836} \\\\ {\rightarrow x=\sqrt{15836}} \\\\ {\rightarrow x=125.841}\end{array}$

So, the adjacent side value is 125.8 inches approximately.

Hence the steps to find adjacent side is shown above

Now let us find cos, sin and tan

$\begin{aligned} \sin \theta &=\frac{\text {opposite side}}{\text {hypotenuse}} \\\\ \cos \theta &=\frac{\text {adjacent side}}{\text {hypotenuse}} \\\\ \tan \theta &=\frac{\text {opposite side}}{\text {adjacent side}} \end{aligned}$

By substituting the required values, we can find cos, sin and tan

$\begin{array}{l}{\sin \theta=\frac{70}{144}=\frac{35}{122}} \\\\ {\cos \theta=\frac{125.8}{144}=\frac{62.9}{122}} \\\\ {\tan \theta=\frac{70}{125.8}=\frac{35}{62.9}}\end{array}$

3. Evaluate the expression (-10) - (-4)

STatiana [176]

Answer:

-6

Step-by-step explanation:

(-10) - (-4)

-10 +4 (because negative multiply by negative is positive)

= -6 (because -10+4 means different signs means you subtract and get the sign of the bigger number)

Your parents give you $20 to help buy the new pair of shoes shown. After you buy the shoes, you have $5.50 left. How much money

Mandarinka [93]

Answer:

$45.45

Step-by-step explanation:

Please find attached an image of the shoe that was used in answering this question

From the image, the price of the shoe is $59.95

Let x be the amount you had with you

The equation that would be used to solve this question is :

(x + 20) - $59.5 = $5.50

Solve for x

x = $45.45

If y = 7 what is the slope

lozanna [386]

Since y=7 without depending on the coordinate of x, y=7 everywhere.
This means that it is a horizontal line 7 units above the x-axis.
A horizontal line has a slope of zero.
