Quadrilateral PQRS is a rectangle. What is the length of PQ? Select the best answer from the choices provided.
А.7
B.19.799
C.24.249
D.28

C

Step-by-step explanation:

remember SOHCAHTOA

SOH is for sin

CAH is for cosin

TOA is for tan

line PS=14 so line QR=14

line PQ is your x value. so to solve, write out tan30=14/x

rewrite it so it now says x= 14/tan. type that in to your calculator and you get your answer

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2
