I know this answer but i don't know how do the workings to get the answer. So far, none of my workings have been able to lead me to the correct answer. Please can any one show me the workings?

a) Each vertex angle of the regular n-gon measures (n-2)*180/n degrees. Since each isosceles triangle uses one vertex angle, the measure of the vertex angle of each isosceles triangle is (n-2)*180/n degrees. b) The base angles of each isosceles triangle are congruent. Since the vertex angle measures (n-2)*180/n degrees, and the three angles of a triangle sum to 180 degrees, each base angle measures (180 - (n-2)*180/n)/2 = (180/n) degrees. c) Let's draw a diagram. If s is the length of each side of the regular n-gon, then the base of each isosceles triangle is s. Using trigonometry, the altitude h to the base bisects the vertex angle, so: h/s = sin((n-2)*180/2n) h = s*sin((n-2)*180/2n) d) The area of each isosceles triangle is (1/2)*b*h = (1/2)*s*[s*sin((n-2)*180/2n)] = (1/2)*s^2*sin((n-2)*180/2n). e) There are n isosceles triangles that make up the regular n-gon. So the total area is: A = n*(1/2)*s^2*sin((n-2)*180/2n) = (1/2)*n*s^2*sin((n-2)*180/2n) 1 Like |

I think say you were confused on the total amount for one bag of rice, chicken, vegetable oil. This kind of questions contributes to the taking down of Nairaland by the host |

bandOFhorses:These are the correct answers but the thing is that I'm having problems arriving at the answers.

turmacs: Let one vertex angle be V And One base angle be b then 2b = ((n-2) X 180) + n |

Re: Who Can Help Me With This Maths , I Don't Understand This. Maths people come in by Wizyoung(m): 9:57pm On Dec 22, 2023 |
But 2b + V = 180 (sum of angles in a triangle) Then V = 180 - ((n-2) X 180)÷n) On simplifying, V = (180n - 180n + 360)÷n V = 360/n |

turmacs: No vex... I forgot to divide the sum of interior angle by n. If you do the division, you'd arrive at the correct answer as shown from my solution above. You need to be polite towards people attending to your queries though. 1 Like |

(b) V+2b = 180 2b = 180 - V b = (180- 360/n)/2 b = (180n - 360)/2(n) b = 180(n-2)/2(n) Finally, b = 90(n-2)/n |

turmacs:a. Let the vertex angle be x. The sum of all the vertex angles is 360 i.e angles at a point. => n * x = 360 x=360/n b. Let the base angle be y Then, y+y+x=180 2y+x=180 2y=180-x= 180-360/n y=90-180/n c. Let altitude be h Tany= opposite side/adjacent side Opposite side=h, Adjacent side= s/2 => Tan y= h/(s/2) Tan(90-180/n) =2h/s h=(s/2)*(tan(90-180/n)) d. Area of triangle= 1/2*base* height = 1/2* s*h =1/2*s*(s/2(tan(90-180/n)) = ((s^2)/4)*(tan(90-180/n)) e. The area of poligon = n* area of triangle area of poligon= (n(s^2)/4)*(tan(90-180/n)) |
