What is the probability of rolling a die and having it land on a factor of 30?
Daniel [21]

Answer:

So, since there is an equal chance to roll any number on a six sided die, that means the chance of rolling any one number is one out of 6 or 1/6. You can see that with a diagram. Now, rolling two different numbers in a specific order you can tell with a diagram is 1/36.

Which quadrant 20 degree in ?
elena55 [62]

Answer:

Therefore 20 degree is in First Quadrant,

i.e Quadrant I.

Step-by-step explanation:

QUADRANT:

When the terminal arm of an angle starts from the x-axis in the anticlockwise direction then the angles are always positive angles.

Quadrant I      -          0° to 90°

Quadrant II     -       90° to 180°

Quadrant III    -      180° to 270°

Quadrant IV    -      270° to 360°

Therefore 20 degree is in First Quadrant, i.e Quadrant I.

When the terminal arm of an angle starts from the x-axis in the clockwise direction than the angles are negative angles.

Quadrant IV  -          0° to -90°

Quadrant III   -       -90° to -180°

Quadrant II    -      -180° to -270°

Quadrant I     -      -270° to -360°

Find the area of the the regular polygon.
VARVARA [1.3K]

Answer:

<em>Area of Regular Polygon = ( About ) 332.6 units^2; Option C</em>

Step-by-step explanation:

<em>~ Let us first declare consecutive notes. If we were to draw an altitude in this triangle, it would be perpendicular to the base, by definition. At the same time this shape is a regular polygon, so all sides ( and angles ) are ≅. This would mean that, by Coincidence Theorem, the altitude divides the base into the two ≅ parts. ~</em>

1. If that is so, the altitude would split this base into parts ⇒ ( 16√3 )/2 = 8√3.

2. This would mean that the altitude can be found through Pythagorean Theorem, provided that by definition it forms a 90 degree angle at the base. Let us say x ⇒ the length of the altitude, ( 8√3 )^2 + ( x )^2 = ( 16√3 )^2 ⇒ 192 + x^2 = 768 ⇒ x^2 = 576 ⇒ length of altitude - 24 units

3. With the base 16√3 units, and the the altitude/height 24 units, we can find the area of this regular polygon to be ⇒ 1/2 * base * height ⇒ 1/2 * 16√3 * 24 ⇒ 192√3 units^2

4. That being said that area would be 192 * 1.732050808...... ⇒

<em>Area of Regular Polygon = ( About ) 332.6 units^2</em>
