r + 4(r - 3)

<em><u>We'll use the distributive property to simplify this.</u></em>

r^2 - 3r + 4r - 12

<u><em>Combine like terms</em></u>

r^2 + r - 12 is the simplified form.

Solve equation if 0 degrees is less than or even to x which is less than or equal to 360 degrees
Elena L [17]

Answer:

x = 60°

Step-by-step explanation:

Use special triangles.

Starting with an equilateral triangle (all angles at 60°) with the side length of 2. Drop an altitude from one of the vertices to cut in half and make a right - triangle.

The hypotenuse length is 2. The base length, because it was cut in half, is 1. The height can be found with the Pythagorean theorem, which is √3.

The ratio for tangent is opposite over adjacent.

Since √3 = √3 / 1, the angle must be the one as marked in the picture.

Remember this triangle came from an equilateral triangle, so that angle is 60°. It was not cut in half, unlike the top angle which is 30°.
