Answer:
a = and b =
Step-by-step explanation:
As we know, the radius of the unit circle is 1 unit (it is the hypotenuse in the right triangle, the blue line)
We use trigonometric formulas to find out a and b
<=> Sin(45) = b / 1
<=> b= Sin(45)*1 =
<=> Cos(45) = a / 1
<=> a = Cos(45)*1 =
So: a = and b =
Answer:
the lines represent absolute value bars
Step-by-step explanation:
STEP 1: Move all terms not containing |5−x| to the right side of the equation.
STEP 2: Divide each term by 3 and simplify.
STEP 3: Remove the absolute value term. This creates a ± on the right side of the equation because |x|=±x.
<em>5-x=±5</em>
STEP 4: Set up the positive portion of the ± solution.
STEP 5: Solve the first equation for x.
STEP 6: Set up the negative portion of the ± solution.
STEP 7: Solve the second equation for x.
NOTE: The solution to the equation includes both the positive and negative portions of the solution.
