Consider the figure below. abraham cut regular pentagon abcde into quadrilateral begc. which of the following statements is true about quadrilateral begc? (picture included)

Let 'n' be the number of side of a regular polygon each angle are equal and sum of  each angle equal to (n-2)×180. ∴For a regular pentagon have five equal side, n=5 ∴ sum of each angle = (n-2)×180=3×180 = 540. and ecah angle = 540÷5=108°. Therefore ∠BCG = 108° and ∠ABC =108° Here BE is one of the diagonal of regular pentagon ABCDE. BE divide ∠ABC in 1:2 ratio Therefore ∠ABE : ∠CBE = 36: 72∴ ∠GCB + ∠CBE = 108° +72°=180°

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
