Step-by-step explanation:

Using the sine or cosine ratio in the right triangle and the exact value

sin30° = \frac{1}{2} , then

sin30° = \frac{opposite}{hypotenuse} = \frac{4}{x} = \frac{1}{2} ( cross- multiply )

x = 8

Multiply the polynomials (x + 4)(x + 4)
s2008m [1.1K]

Answer:

x^2 + 8x + 16

Step-by-step explanation:

(x + 4) (x+ 4) multiply x by x and x by 4.

x^2 + 4x

Then multiply 4 by x and 4 by 4.

4x + 16

Then combine like terms.

x^2 + 4x + 4x +16

x^2 + 8x + 16

A skateboarding ramp is 13in. high and rises at an angle of 13°. How long is the base of the ramp? Round to the nearest inch.
charle [14.2K]
<h3>Answer:  Approximately 56 inches</h3>

===========================================================

Explanation:

The diagram is shown below. We know the vertical part of the triangle is 13 inches, which is the side opposite the reference angle 13 degrees. The adjacent side is unknown. We'll call it x. This is how long the base of the ramp is, which is the horizontal distance along the entire ramp. This distance is on the ground. The ramp itself is the hypotenuse but it seems like your teacher isn't wanting to know this value. So we'll ignore the hypotenuse.

We'll use the tangent rule to connect the opposite and adjacent sides.

tan(angle) = opposite/adjacent

tan(13) = 13/x

x*tan(13) = 13

x = 13/tan(13)

x = 56.309186365694

x = 56 inches is the approximate horizontal distance underneath the ramp
