Quadrilateral WXYZ is on a coordinate plane. Segment XY is on the line x â’ 3y = â’12, and segment WZ is on the x â’ 3y = â’6. Which statement proves how segments XY and WZ are related? They have opposite reciprocals slopes of one third and â’3 and are, therefore, perpendicular. They have the same slope of negative one third and are, therefore, parallel. They have opposite reciprocals slopes of negative one third and 3 and are, therefore, perpendicular. They have the same slope of one third and are, therefore, parallel.

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.
