Answer:
Hector
Step-by-step explanation:
The are parallel because they go in the same directions and they are line segments because technically a true line is infinitely long.
Multiply the second equation by 3
-4x+9y=9
3x-9y=-18
add the equations together
-x=-9 Simplify
x=9
now plug in your x value
(9)-3y=-6 Simplify
-3y=-6-9
-3y=-15
y=5
Answer:
Step-by-step explanation:
9+9=18
Answer:
Step-by-step explanation:
Law of sines says that the length of sides are proportional to the sine of the opposing angle.
Using the sine rule,
sin(x)/2.5 = sin(28)/3
therefore
sin(x) = 2.5 * sin(28) / 3
or
here we have
x = asin (2.5*sin(28) / 3)
so
box 1 = 2.5
box 2 = 28°
box 3 = 3
