I just took the 16 chairs and added 2 since thats how many are left over, then since adding these 16 chairs, you are creating 2 more rows, so (16+2)/2 =9 Therefore, each row must have nine chairs in it and Hue starts off with 5x9+2= 47 chairs
Answer:
on a triangle the bottom is always smaller then the two sides , also the two sides should be equal unless it an isosceles triangle. <3 I hope this helps .
5/4 could be multiplied by each side for x=10. D is your answer.
Let A, B, C, D, E be the given points in order.
AB=4-1=3
BC=√((7-4)²+(2-(-2))²)=√(9+16)=√25=5
CD=BC=5
DE=4-1=3
AE=6-(-2)=8
Perimeter=3+5+5+3+8=24.
Please note that in proving this, I have used trigonometric identities other than just the sine angle-addition formula.
