Find the length of side XZ to the nearest meter.

13 meters.

Step-by-step explanation:

Side XZ is the hypotenuse, so that is side H.

Side XY is the adjacent side, so that is side A.

This becomes easy if you have learned the SOHCAHTOA method- we have H and a so we use C, for cosine.

Cosine 48= 9/XZ

Cosine 48 (XZ)=9

XZ=9/Cosine 48

XZ=13.45 meters

So, to the nearest meter XZ is 13 meters.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

(-5,-28)
