Find the area of a regular polygon

Mathematics
1 answer:
Dimas [21]3 years ago
4 0

Answer:

(N-2)x180=sum of interior angles

So (5-2)x180=540

Divided by number of sides=540/4=108... then each angle is 108 divide to triangles ..so they will have 2 angles =54 2 sides =4 the last angle =72 ."of the triangle " area of triangle =1/2xsxsxsin(side in

between)

So 1/2x4x4xsin(72)= then multiply it by 5 as u will have 5 triangles .. so it will be 190.2(probably i tried)

Mount everest is 8847 m high. how many centimeters high is the mountain
nata0808 [166]
Before we answer the question we must first:
1. Assess what we have so far.
2. Know what we need to find.
3. Solve.
4. Conclude.

Step 1: What we have so far.
*Mt. Everest's height in meters (m) =  <span>8847m

Step 2: What we need to find.
*</span>Mt. Everest's height in centimeters (cm) = ?

Step 3: Solve.
*Centi means 100.
*1m = 100cm

Conversion process:
8847m x 100cm/1m <--- we need to multiply Mt. Everest's height to 100cm/1m first because our first agenda is to remove (m) from the value.
8847 x 100cm <--- this will be our working solution.
884,700cm <--- Answer

Step 4: Conclusion.
After successfully doing the steps above, we can now conclude that the height of Mt. Everest in centimeters is: 884,700cm

I need to know the answer now
Wewaii [24]

Um, ok I'm not entirely sure what number sets you need, but I'll do my best.

Integers: 5, -3, 0, 1, -12

Fractions: 1/2, 4 1/2

Decimals: 14.2, -19.4, 0.125

All of the above can also be considered Rational numbers. Rational numbers are numbers that can be expressed as a fraction. All For example, 14.2 is 14 1/5.

Irrational number: \pi

Pi is irrational. It cannot be expressed as a fraction.

Point A is (-6,-5) Point C is (4,0) Find the coordinates of point B on AC such that the ratio of AB to BC is 2:3.
Fed [463]

Answer:

(-2, -3)

Step-by-step explanation:

x coord. from -6 to 4 is 10 units / 5 parts = 2

point B is 2 units * 2 from point A, so x = -2

y coord. from -5 to 0 is 5 units / 5 parts = 1

point B is 2 units * 1 from point A, so y = -3
