Answer:
44 units
Step-by-step explanation:
Since B is the mid-point of AC
AB=BC
or,4x+14=x+20
or, 4x-x=20-14
or 3x=6
or,x=6/3=2
AC=AB+BC
= 4x+14+x+20
= 4(2) + 14 +2 +20
= 8+14+22
=44 units

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) = opposite side / hypotenuse
<=> Sin(45) = b / 1
<=> b= Sin(45)*1 =
- Cos(45) = adjacent side / hypotenuse
<=> Cos(45) = a / 1
<=> a = Cos(45)*1 =
So: a = and b =
