Answer:
16+x
Step-by-step explanation:
So 2x+12=5x-9
you want all of the unknowns on one side and all of the known values on the other or
subtract 2x from both sides
12=3x-9
add 9 to both sides
21=3x
divide both sides by 3
7=x
By Sine Rule,
x/sin30° = 8/sin90°
x/0.5 = 8/1
So x = 4.
Answer:
Step-by-step explanation:4 -2x=3x +2
4-2=3x+2x
2=5x
X=2/5
This is a square, and so all the sides will be the same measurements. Note that you are given an area, so you'll have to root the total area to get a side.
√400 = 20
One side's measurements is 20 in
