Answer:
2 and 1
Step-by-step explanation:
apsolute value is always a positive number.
If you're supposed to find the measure of the arc:
The minor arc CD has the same measure as the central angle it subtends. In this case, arc CD has measure 50º. In radians, that's
50º * (π/180 rad/º) = 5π/18 rad
If you instead meant to ask about finding the length of the arc CD, recall that arc lengths and their subtended central angles occur in a fixed ratio equal to the ratio of the circle's total circumference to 2π rad. In other words, if <em>L</em> is the length of the minor arc CD, then
<em>L</em> /(5π/18 rad) = 2π (7 cm) / (2π rad)
==> <em>L</em> = 35π/18 cm
(Notice that arc measure is given radians, while arc length is given in cm, which is why I offer two different answers here.)
D2 - d + 4d = d2 - 8d
d2 + 3d = d2 - 8d
d2 - d2 = - 8d - 3d
0 = - 11d
Answer:
Step-by-step explanation:
Yara=x goals
Natasha= x+8
Emma=2x
Add these
X+x+8+2x=4x+8
4x+8=52 -8
-8 both sides
4x=44
X=11
Yara 11 goals
Natasha 9 goals
Emma 11×2=22 goals hope this helps
