Answer:
x = 12
Step-by-step explanation:
Angle GHK is half of 120, so is 60. Then ...
3x +24 = 60
3x = 36 . . . . . subtract 24
x = 12 . . . . . . . divide by 3
Check the picture below.
the triangle is an isosceles, so it has twin legs, and a base bottom.
the twin sides stem from the "vertex", and we know the vertex is 120°, and since the triangle is inscribed in a circle, because the circle is "circumscribing" it, then the base side of the triangle will be the diameter of it.
if we run a perpendicular line to the base from the vertex, we'll split the vertex in two 60° angles, as you see there, giving us a 30-60-90 triangle on each side.
so, anyhow, the rest is just a matter of using the 30-60-90 rule.
that's the diameter, and as you know, the radius is just the length of the base, or half the diameter.
You buy 6 shirts. So $77 minus $5=$72
Then you divide $72 by $12 and you get 6 shirts
Answer:
Step-by-step explanation:
I=PRT/100
40=(500XRX2)/100
R=(40X100)/500X2
R=4000/1000
R=4 percent/annum
