Add 1 to both sides of the equation to get 4x = 4.
Divide both sides by 4 and <em>x = 1</em>.
Answer:
Step-by-step explanation:
So you can use the special formula for 30-60-90 triangle or you can use the whole Soh Cah Toa thing.
I honestly prefer trig. so a is the opposite side of the 30 deg and 12 is the hyp. This should scream sine to you since sine goes with opposite/hypotenuse.
sin(30 deg)=a/12
Multiply both sides by 12
giving a=12 sin(30)
Type into calculator unless you know your unit circle well.
a=6
In the proportional theory,
28 units is the total measurement that includes 8 units.
So, 10 + 3x - 5 is the total measurement that includes 10 units proportionally.
This means,
28 = 10 + 3x - 5
Now solve for x,
28 = 10 + 3x - 5
28 - 10 = 3x - 5
18 + 5 = 3x
23 = 3x
23 / 3 = x
So x = 23/3 or 7.6666....
