Find the area of this regular polygon (trigonometry) !!! Please and thank you !! Bogus answers reported

777dan777 [17]

If we join the Center with different corners of the polygon,we find 10 Isoceles triangle with equal side=9.14cm, Making an angle of 36° between the equal sides.

Area of 1 triangle= a*b*sinC/2
= 9.14*9.14*Sin36°/2
= 9.14*9.14*0.587/2
=24.51 cm^2

Area of 10 triangle= 24.51*10
= 245.1cm^2

Match each equation with the slope m and y-intercept of its graph.

Svetllana [295]

m=-6 and y-int of (0,5) gives you y = -6x + 5.

Looking through those other equations, you're looking for variations of that equation.

#1 is NOT.

#2 IS, because -6x + 5 is the same as 5 - 6x.

#3 is NOT.

#4 is NOT.

#5 is NOT.

#6 is NOT.

It looks like #2 is the only one.

Answer:

29 $\sqrt{5}$

Step-by-step explanation:

11 $\sqrt{9*5}$ - 4 $\sqrt{5}$

Take nine out - square root of 9 is 3

= 3 x 11 $\sqrt{5}$ - 4 $\sqrt{5}$

= 33 $\sqrt{5}$ - 4 $\sqrt{5}$

= 29 $\sqrt{5}$

can not be simplified any more

Answer:

A) 10

Step-by-step explanation:

Let the first integer be $a+1$ . Then we wish to solve for the following:

$(a+1) + (a+2) + \cdots + (a + n) + 100 = (a + (n + 1)) + (a + (n + 2)) + \cdots + (a + (2n))\\10a + (1 + 2 + \cdots + n) + 100 = 10a + ((n + 1) + (n + 2) + \cdots + (2n))\\\frac{1}{2}(n)(n + 1) + 100 = \frac{1}{2}(n)(3n + 1)\\n(n + 1) + 200 = n(3n + 1)\\n^2 + n + 200 = 3n^2 + n\\2n^2 = 200\\n^2 = 100\\n = 10 \quad \text{(because $n > 0$)}$
