Answer:

Cosine

Step-by-step explanation:

Cosine = $\frac{adjacent}{hypothenuse}$

Cos 70 = $\frac{x}{8}$

0.633 = $\frac{x}{8}$

0.633 x 8 = $\frac{x}{8}$ x 8

Answer:

Cosine.

Step-by-step explanation:

Hypotenuse : Opposite the right angle

Opposite : opposite the angle

Adjacent : The only side left

Soh (sin) Cah (Cos) Toa (Tan)

Hypotenuse and adjacent are the only ones that have a side on them

so h and a. Cah Cosine Adjacent and hypotenuse. Cosine

Please help!! I don't know what to do :(

Yo sup??

This question can be solved by applying the properties of similar triangles

the triangle with sides 5x and 20 is similar to the triangle with sides 45 and 36

therefore we can say

5x/45=20/36

x=5 units

Hope this helps

How is solving an inequality like solving an equation? How is it different?

Charra [1.4K]

Answer:

The only difference is: If you multiply or divide both sides of an equation by the same negative number, the equation remains the same, but If you multiply or divide both sides of an inequality by the same negative number, the inequality reverses.

Identify the x- and y- intercepts of this equation. 5 − 4 = 20

Alinara [238K]

T he x and y intercepts of the equation: $5x-4y=20$ are : y-intercept is (0,-5) and x-intercept is (4,0)

So, Option D is correct.

Step-by-step explanation:

we need to identify the x and y intercepts of the equation: $5x-4y=20$

Finding x-intercept

For finding x-intercept put y=0

We are given the equation:

$5x-4y=20$

Solving:

$5x-4y=20\\5x-4(0)=20\\5x=20\\x=\frac{20}{5}\\x=4$

So, x-intercept is (4,0)

Finding y-intercept

For finding y-intercept put x=0

We are given the equation:

$5x-4y=20$

Solving:

$5x-4y=20\\5(0)-4y=20\\-4y=20\\y=\frac{20}{-4}\\y=-5$

So, y-intercept is (0,-5)

the x and y intercepts of the equation: $5x-4y=20$ are :y-intercept is (0,-5) and x-intercept is (4,0)

So, Option D is correct.
