hello again I need to find an equation to find the long side of the triangle. but this time only the hypotenuse is given. brainl

Hunter-Best [27]

Answer:

The answer to your question is Long = 10.39

Step-by-step explanation:

Data

hypotenuse = 12

long = ?

Process

1.- To find Long, we must use the trigonometric functions sine or cosine.

If we use sine, we use the 60° angle

If we use cosine, we use the 30° angle

a) sin 60 = long / hypotenuse

Long = hypotenuse x sin 60

Long = 12 x sin 60

Long = 10.39

b) cos 30 = Long / hypotenuse

Long = hypotenuse x cos 30

Long = 12 x cos 30

Long = 10.39

Ava used the following equation in order to solve a math problem involving integers.

AnnZ [28]

Answer:

The only equation which is incorrect is in option B.

Step-by-step explanation:

Eva used the following equation in order to solving integers, which is

$\frac{-h}{-k} = j$

⇒ $j = \frac{h}{k}$ ......... (1)

Now, if the equation Ava used is correct, then we have to find which of the given equations is not correct.

Now, in option A) it is given that $- j = \frac{- h}{k}$

⇒ $j = \frac{h}{k}$ which is same as equation (1).

In option B) it is given that $- j = \frac{- h}{- k}$

⇒ $j = - \frac{h}{k}$ which is not same as equation (1).

In option C) it is given that $- j = \frac{h}{- k}$

⇒ $j = \frac{h}{k}$ which is same as equation (1).

Again, in option D) it is given that $j = \frac{h}{k}$

⇒ $j = \frac{h}{k}$ which is same as equation (1).

Therefore, the only equation which is incorrect is in option B. (Answer)
