A = (1/2)asn, where "a" is the length of the apothem, "s" is the length of each side, and "n" is the number of sides.

Vertical angles are a pair of nonadjacent angles, ∠1 and ∠2, formed by two intersecting lines. A linear pair is two adjacent angles, ∠3 and  ∠4, formed by opposite rays.    Thus, the vertical angles are not also a linear pair.

Let x = the number of child tickets Let y = the number of adult tickets x + y = 14       x = 14 - y 5x +9y = 110 5(14 - y) + 9y = 110 70 - 5y + 9y = 110 4y = 40 y = 10 x = 14 - 10 = 4

h = -16t2 + 112t 0 = -16t2 + 112t 0 = -16t(t - 7) t - 7 = 0 t = 7 seconds

There was no figure below. Let w = the width Let w + 7 = the length A = lw 21 = w(w + 7) 21 = w2 + 7w w2 + 7w - 21 = 0     Use the quadratic formula.   w = -7 ± √[72 - 4(1)(-21)]          ...

I guess your question is how much money will he have at the end of three years. A = P(1 + r/n)nt A = 1000(1 + .05/2)2(3) A = 1000(1.025)6 A = 1000(1.1597) A = $1159.69    

Let x = the angle Let 90 - x = the complement Let 180 - x = the supplement 5(90 - x) = 2(180 - x) + 6 450 - 5x = 360 - 2x + 6 -3x = -90 x = 30º 90 - x = 60º 180 - x = 150º
