(sorry) 70-20-20=30
30÷2=15
20×15= 300
300m is your answer (I hope this is right)

70-20-20 = 30 divided by 2 equals 15 so 15 is the width use that in the equation.
Area = 20 x 15
Area = 300m squared

Answer:

Yes, i believe that the generalization about the measure of a point angle of a star polygon is true.

First we find sum of interior angle of an n-sided star polygon.

number of triangle in a polygon = n - 2

sum of interior angle of a triangle = 180°

sum of interior angle of an n-sided star polygon = ( n - 2 ) × 180°

To find measure of a point angle, we use:

\frac{|n-2(d)|}{n} × 180°                                                            

To find a point angle we eliminate density by multiplying d by 2  in the formula for finding number of triangle, divide the whole by total number of sides and then multiply by the sum of interior angle of triangle(180°).  

Since all the angle of a regular star polygon are equal, we can calculate each pointy interior angle of a regular star polygon using the formula given below:

\frac{|n-2(d)|}{n} × 180°

Answer:

∠ 3 = 25°

Step-by-step explanation:

The sum of the 3 angles 85, 2x and x - 10 are a straight angle = 180°

85 + 2x + x - 10 = 180, that is

3x + 75 = 180 ( subtract 75 from both sides )

3x = 105 ( divide both sides by 3 )

x = 35

Thus x - 10 = 35 - 10 = 25

∠ 3 and x - 10 are Alternate angles and congruent, thus

∠ 3 = 25°

An apple is cut into 6 equal slices. nancy eats 2 of the slices .what fraction of the apple is left.math
ValentinkaMS [17]
Cut the apple into pieces. You get 6/6, which is equal to 1 whole apple. Then after Nancy eats 2 of the slices, you subtract 2/6 from 6/6. After this you get 4/6.
4/6 is the fraction of the apple is left
 Not sure if this is high school math though hahah
