You can solve it like that, I don't remember what it is called.
Depends on the size of your desk generally, 2 sheets of paper can easily lay next to each other on a desk and papers are about 8 inches so about 16-20 inches wide of a desk and about 15 inches long
751/5= 150.2 inches too big for desk
751/10=75.1 inches too big for desk
751/500=1.502 feet or 18 inches a bit big for the desk but should be okay
751/5000=.1502 feet or 1.8 inches fits on desk but a bit small
I would go with either 1=5000 or 1=500 because those are the only 2 that would fit on your desk, probably the 1=5000 would be the best answer
Answer:
θ = 18°27'
Step-by-step explanation:
As the hint says, you need to calculate CE using the triangles ΔABC and ΔBDE.
Using segment addition, CE = CB + BE. So first use trigonometry to find these segments.
First, let's find CB.
sin 22° = CB / 4.882
CB = 1.8288
Next, let's find BE.
cos 22° = AB / 4.882
AB = 4.5265
BD = AB − 1.975
BD = 2.5515
tan 48° = BE / BD
BE = 2.8337
Now we can find CE and θ.
CE = CB + BE
CE = 4.6626
cos θ = CE / 4.915
θ = 18.443°
A minute is 1/60th of a degree.
0.443° × (60 '/°) = 27'
So θ = 18°27'.
4(x+2)=3(x-2)
Multiply the first bracket by 4
Multiply the second bracket by 3
4x+8=3x-6
Move 3x to the left hand side, whenever moving a number with a letter the sign changes ( positive 3x to negative 3x)
4x-3x+8=3x-3x-6
x+8=-6
Move positive 8 to the right hand side
x+8-8=-6-8
x=-14
Check answer by using substitution method
Use x=-14 into both of the equations
4(-14+2)=3(-14-2)
-56+8=-42-6
-48=-48
Answer is -14- D)
